LATER UPDATES: A glimpse into the longer term or the current?

Standing: pending


Standing: Printed March 2021, however submitted in April 2020, which suggests many of the analysis was accomplished earlier than the Plandemic.


So the individuals who declare many vaccines are simply saline and the individuals who declare they’re simply graphene oxide may be proper on the identical time.

In case you are studying this, possibilities ae you already know of La Quinta Columna researchers and Stu Peters exhibits that exposed massive presence of very poisonous graphene in Covid injections. Should you don’t, you could analysis and meet up with the small print, there’s no dishonest on the homework anymore.


Onw of Stu’s newest deliveries featured a really documented professional and Pharma analyst who previously labored for Pfizer and revealed the graphene is hiding within the so known as PEGs, I’ll clarify shortly what these are.

So I went to fact-check this, regardless that the whistle-blower sounded very compelling and having deep insights within the enterprise.

My findings present that they solely scratch the floor of a bigger downside:
As I’ve proven earlier than, graphene has a big spectrum of purposes right now, most endangering our well being. However graphene oxide (GO) is very poisonous and they’ll pump it in us with different therapies too.

GO-based PEGs have been the brand new rising star of drug supply for fairly just a few years earlier than Covid and they’re normally graphene primarily based, as a a number of research and invention patents show past doubt. I don’t assume there’s any mRNA vaccine that doesn’t use them.

They don’t seem to be featured in injections inserts as separate ingredient, which they’re, however as a course of. Yup, they’re the PEG in PEGylation.
It’s like saying Coca Cola was sweetened as a substitute of itemizing a number of sweeteners!

Right here you may obtain the security Knowledge Sheet for ALC-0135, it’s unhealthy stuff, actually corrosive!

Moderna comes with the products too, all their invention patents for the mRNA tech comprise these PEGs:

Consider an oral drug capsule. The PEG is a high-nanotech model of the capsule cloth, which may do a sequence of cool methods, however its primarily roles are to guard the content material and assist it penetrate tissue/cells and attain particular targets.

Now assume the drug insert solely lists the content material components. not the capsule.

“Poly(ethylene glycol) (PEG), often known as poly(ethylene oxide) (PEO), is an amphiphilic polyether that’s soluble each in water and most natural solvents. PEG and its derivatives are among the many few polymers permitted for medical makes use of by the FDA.

Functionalized PEG, additionally named activated PEG, is a household of PEG derivatives adorned with purposeful teams. Funtionalized PEGs are used broadly for drug PEGylation, polymer engineering, nantechnology, biotechnology, and biomedical engineering.”
That is the outline given by Sinopeg, Chinese language firm that delivers PEGs for many Covid injection producers.

From their September 2020 weblog publish we extract extra particulars confirming my earlier claims:

“The coupling of PEG to protein can also be known as protein polyglycolization, which is actually a drug supply expertise. The coupling of activated peg with protein molecules can enhance the three-dimensional area state of proteins, leading to adjustments in numerous biochemical properties of proteins. For instance, chemical stability elevated, half-life extended, immunogenicity and toxicity decreased or disappeared, protein solubility elevated. SINOPEG is a dynamic science firm devoted to drug supply techniques (DDS). SINOPEG are specialised within the R&D of lengthy appearing biopharmaceuticals, growing and manufacturing of block copolymers, lipids for drug supply, medical units, bio-engineering, and different broad makes use of.

To this point, the FDA has permitted 20 polyglycolic medication. Along with monoclonal antibodies, polyglycolic medication have develop into essentially the most highly effective drug growth expertise.
As a number one firm in polyethylene glycol derivatives (PEGs), SINOPEG is able to supplying small to massive portions of wealthy choice of PEG spinoff merchandise with distinctive molecular designs (chemical construction, molecular weights (MW)) and distinctive product high quality management to serve bio-technology and pharmaceutical corporations and analysis organizations worldwide.”

At this level, you’re in all probability asking when is graphene coming in. I obtained you coated:

Graphene oxide (GO) is thought to strongly bind single-stranded nucleic acids with fluorescence quenching close to the GO floor. Nonetheless, GO reveals weak biocompatibility traits, reminiscent of low dispersibility in cell tradition media and vital cytotoxicity. To enhance dispersibility in cell tradition media and cell viability of GO, we ready nanosized GO (nGO) constructs and modified the nGO floor utilizing polyethylene glycol (PEG-nGO). Single-stranded peptide nucleic acid (PNA) was adsorbed onto the PEG-nGO and was readily desorbed by including complementary RNA or underneath low pH circumstances. PNA adsorbed on the PEG-nGO was effectively delivered into lung most cancers cells through endocytosis with out affecting cell viability. Moreover, antisense PNA delivered utilizing PEG-nGO successfully downregulated the expression of the goal gene in most cancers cells. Our outcomes recommend that PEG-nGO is a biocompatible service helpful for PNA supply into cells and serves as a promising gene supply software.

Hyo Ryoung Kim 1, Ahruem Baek 1, Il Joon Lee 1, Dong-Eun Kim 1


Polymerase chain response (PCR), a flexible DNA amplification methodology, is a elementary expertise in fashionable life sciences and molecular diagnostics. After a number of rounds of PCR, nevertheless, nonspecific DNA fragments are sometimes produced and the amplification effectivity and constancy lower. Right here, we demonstrated that poly(ethylene glycol)-engrafted nanosized graphene oxide (PEG-nGO) can considerably enhance the PCR specificity and effectivity. PEG-nGO permits the specificity to be maintained even after a number of rounds of PCR, permitting dependable amplification at low annealing temperatures. PEG-nGO decreases the nonspecific annealing of single-stranded DNA (ssDNA), reminiscent of primer dimerization and false priming, by adsorbing extra primers. Furthermore, PEG-nGO interrupts the reannealing of denatured template DNA by preferentially binding to ssDNA. Thus, PEG-nGO enhances the PCR specificity by preferentially binding to ssDNA with out inhibiting DNA polymerase, which is analogous to the function of ssDNA binding proteins.

Methodology and course of to make and use cotton-tipped electrochemical immunosensor for the detection of corona virus United States Patent 11035817



A technique and course of to make and use cotton-tipped electrochemical immunosensor for the detection of corona viruses is described. The immunosensor had been fabricated by immobilizing the virus antigens on carbon nanofiber-modified display printed electrodes which had been functionalized by diazonium electrografting and activated by EDC/NHS chemistry. The detection of virus antigens had been achieved through swabbing adopted by aggressive assay utilizing mounted quantity of antibody within the resolution. Ferro/ferricyanide redox probe was used for the detection utilizing sq. wave voltammetric method. The boundaries of detection for our electrochemical biosensors had been 0.8 and 0.09 pg/ml for SARS-CoV-2 and MERS-CoV, respectively indicating superb sensitivity for the sensors. Each biosensors didn’t present vital cross reactivity with different virus antigens reminiscent of influenza A and HCoV, indicating the excessive selectivity of the strategy.


The newly recognized extreme acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is the final found member of the corona viruses that trigger severe human respiratory infections. Different varieties of corona viruses had been beforehand identified such because the Center East respiratory syndrome coronavirus (MERS-CoV), SARS-CoV1, HCoV-OC43, HCoV-229E, HCoV HKU1 and HCoV NL63. Since its first identification in China in 2019 till current, SARS-CoV-2 has unfold globally inflicting vital morbidity and mortality. COVID-19; the illness attributable to SARS-CoV-2; was declared as pandemic by the world well being group on March 2020. Till now, there aren’t any obtainable vaccines or medication confirmed to deal with COVID 19. Subsequently, the well timed detection of SARS-CoV-2, is urgently wanted to successfully management the fast unfold of the an infection.

The testing of the virus may be achieved by reverse transcription polymerase chain response (RT-PCR) take a look at, detection of antigens, or by serological testing (the detection of the virus antibody). Nonetheless, the serological exams will not be dependable for the early prognosis of SARS-CoV-2 an infection as a result of comparatively lengthy delay between an infection and seroconversion. Molecular prognosis utilizing RT-PCR is the first used methodology for the detection of corona viruses. Nonetheless, PCR takes comparatively very long time for evaluation (minimal of three hours), and requires a number of steps together with the gathering of the specimens by swabbing, the transport of the pattern into an answer and extraction of the viral RNA earlier than amplification. Furthermore, RT-PCR is comparatively costly which hindered its extensive applicability for inhabitants scale prognosis of SARS-CoV-2, notably in low and center revenue nations. Thus, delicate, fast and correct diagnostic strategies primarily based on the direct detection of the viral antigens with out pretreatment is extremely demanded to regulate the COVID 19 outbreak. There are 4 essential structural antigens for corona viruses: nucleocapsid (N), spike (S), matrix (M), and envelope (E). Amongst them, the S and N proteins have the potential for use as biomarkers as a result of they’ll distinguish various kinds of corona viruses.

A number of diagnostic strategies are being developed for the detection of COVID 19. Biosensors have been extensively used for a lot of diagnostic purposes exhibiting quick, simple and dependable detection. Till now, solely few biosensors have been developed for SARS-CoV-2 such because the graphene-based field-effect transistor (FET) biosensor reported by Search engine optimisation. et al. The FET immunosensor was used for the detection of SARS-CoV-2 utilizing spike 51 protein as biomarker. Plasmonic photothermal biosensors for SARS-CoV-2 by means of nucleic acid hybridization have been additionally developed. Half-strip lateral movement assays (LFA) for the detection of N protein was reported. Nonetheless, LFA present qualitative or semi-quantitative outcomes and extra work continues to be required to develop extra correct detection strategies.

Electrochemical biosensors are one of the vital common varieties of biosensors which provide a number of benefits such because the low price, functionality of miniaturization, excessive sensitivity and selectivity. These benefits make them best to be used as point-of-care units for diagnostic purposes. Electrochemical biosensors have been extensively built-in with carbon nanostructures to manufacture extremely delicate units. Carbon nanofiber (CNF) is without doubt one of the supplies that confirmed wonderful purposes in biosensors due to its massive floor space, stability and ease of functionalization.

Cotton swabs have been just lately used within the fabrication of immunoassays for the detection of various pathogens. In these assays, the colorimetric detection was achieved primarily based on visible discrimination of the colour change. These assays are easy, quick and simple to carry out. Nonetheless, they solely give qualitative or semi-quantitative outcomes. Thus, extra correct strategies are nonetheless required.

1. Subject of the Invention

The current invention pertains to a composition for PCR together with polyethylene glycol-engrafted nano-sized graphene oxide (PEG-nGO), the composition for PCR being able to growing the effectivity and specificity of PCR and shortening PCR time, and a PCR methodology utilizing the identical.

2. Dialogue of Associated Artwork

Polymerase chain response (PCR) is a technique of artificially amplifying DNA and is an indispensable expertise in fashionable biotechnology and molecular biology. PCR is extensively utilized in diagnostics, gene manipulation, biosensors, and quite a lot of fields. Nonetheless, the specificity and effectivity of PCR could also be diminished on account of unintended (re)annealing of single stranded DNA (e.g., primer dimerization, incorrect primer binding, and reannealing of PCR amplicons). Nonspecific primer binding in PCR steps might lead to technology of numerous nonspecific amplicons, which may be confirmed by agarose gel electrophoresis. That’s, smearing of a PCR band, which is noticed in an electrophoresed agarose gel, signifies the presence of numerous DNAs having comparable sizes (i.e., nonspecific amplicons). When a DNA template is excessively amplified in PCR and the identical primers are used within the second or subsequent PCR, nonspecific amplicons could also be generated. To unravel these issues, numerous PCR methods reminiscent of nested PCR have been developed. In step one of nested PCR, a primer set for amplifying a broad vary together with a goal sequence on a DNA template is used, and within the second step, primer sequences for amplifying solely the goal sequence are typically used as an inside primer (nested primer) set.

As well as, research have been performed to extend the effectivity and specificity of PCR utilizing numerous nanomaterials reminiscent of gold nanoparticles, carbon nanotubes, carbon nanopowder, graphene nanoflakes, cadmium telluride quantum dots, graphene quantum dots, dendrimers, and titanium dioxide. For instance, graphene nanoflakes serve to enhance PCR effectivity by growing thermal conductivity of a PCR combination, and gold nanoparticles are able to being adsorbed to DNA and proteins to cut back amplification of nonspecific DNA merchandise. Nonetheless, these strategies have an obstacle that the specificity and effectivity of PCR might not be basically solved when every nanoparticle is current. It is usually controversial as as to whether gold nanoparticles play a job in growing the specificity of PCR.

Graphene oxide (GO) refers to a fabric having a honeycomb-like nanostructure during which carbons are organized in a hexagonal lattice, and is ready by oxidizing a single layer of graphite, i.e., graphene. The floor of GO might have numerous purposeful teams reminiscent of epoxy teams, hydroxyl teams, and carboxyl teams, which permit the GO to be dissolved in a water-soluble solvent. As well as, GO might bind to single-stranded nucleic acids through π stacking interplay and hydrogen bonding, however has low affinity to double-stranded nucleic acids. Based mostly on the features of GO, GO has been extensively utilized in numerous areas reminiscent of DNA detection, biosensors primarily based on power switch by means of fluorescence resonance, and real-time monitoring of fluorescently labeled nucleic acids.

Nonetheless, GO is just not soluble in a buffer resolution containing Mg2+ and a excessive salt focus, reminiscent of a PCR buffer, and is adsorbed to proteins reminiscent of a DNA polymerase through non-covalent bonding. It’s well-known that divalent cations reminiscent of Mg2+ induce sturdy crosslinking between GO sheets, permitting the GO sheets to be aggregated. That’s, when different salts are added to a PCR pattern for buffering, GO sheets could also be aggregated by divalent cations reminiscent of Mg2+. As well as, it has been reported that GO is sure to proteins to induce protein aggregation, which can distort the constructions of proteins and trigger the lack of perform of proteins. Polyethylene glycol (PEG) is called a biocompatible polymer that reduces protein adsorption. Not too long ago, to attenuate nonspecific protein adsorption and enhance the solubility of GO in an answer with a excessive salt focus, nano-sized GO (nGO) was ready, and the floor of the nGO was coated with PEG to arrange PEG-nGO (Non-Patent Doc 1). In Non-Patent Doc 1, it’s disclosed that, when PEG-nGO interacts with a protein, a nano-bio interface could also be shaped on account of PEGylation of the floor of GO, thereby considerably lowering adsorption of the PEG-nGO to the protein. Accordingly, PEG-nGO is attracting consideration as a substance able to interacting with proteins with out impairing the construction and performance of the proteins.

Subsequently, the current inventors have tried to verify the impact of PEG-nGO on the effectivity and specificity of PCR. In the course of the denaturation step of PCR, polyethylene glycol-engrafted nano-sized graphene oxide (PEG-nGO) was able to being adsorbed to single-stranded primers and a DNA template. Accordingly, when PEG-nGO was added to a PCR pattern and PCR amplification was carried out, in an preliminary PCR course of during which an extreme quantity of primers was included, primer dimerization was inhibited, and in a late PCR course of during which amplified PCR merchandise had been gathered, nonspecific reannealing between the amplified PCR merchandise and different DNA strands was inhibited. Thus, it was confirmed that, when PCR was carried out utilizing a composition for PCR together with the PEG-nGO of the current invention, the effectivity and specificity of PCR could also be improved and PCR time could also be shortened as in contrast with standard PCR methods. By confirming these outcomes, the current invention was accomplished.

So it shouldn’t shock us that La Quinta Columna ultimately discovered comparable stuff in older vaccines too.

I guess there’s going to be a protracted line of such revelations within the close to future, till they put the shackles on us.

In the meantime, prime researchers from Pakistan and Saudi Arabia discover that GO induces excessive oxidative stress to the cells, slowly killing us:

Different research examine graphene and carbon nanotubes to asbestos:


Extra from the examine quoted above: “Moreover, it’s equally essential that the fabric properties are reported in full in papers coping with (eco)toxicity evaluation of GBMs. Can the knowledge that has been collected on security of GBMs be utilized to different 2D supplies? We imagine that some points is perhaps widespread to all 2D supplies, and even to all nanomaterials, whereas some “postcarbon” 2D supplies will probably current with their very own particular issues. As an illustration, the propensity to dissolve in a organic setting with the discharge of ionic species which are extra biologically/chemically reactive than the parental 2D materials is a matter that has not been described for GBMs.(346) Furthermore, Guiney et al.(347) just lately commented that “with a consistently increasing library of 2D supplies, the power to foretell toxicological outcomes is of crucial significance” and instructed that high-throughput screening approaches might show helpful as a way to elucidate mobile interactions of 2D supplies. Nonetheless, the problem is just not a lot the low throughput of present approaches as a lot because the inconsistent design of generally used toxicity assays and frequent lack of fabric characterization. Certainly, cautious characterization of each the take a look at materials and the take a look at system is required, and a proposal was just lately put ahead for minimal reporting necessities in publications coping with nanobiointeractions. Although such reporting necessities haven’t but been adopted, you will need to talk about these points within the scientific group. To conclude, the hype that inevitably follows with technological advances needs to be tempered by sound, science-based evaluation of the potential influence on human well being and the setting to make sure secure and sustainable growth of recent merchandise and purposes.”

And we discover out the cytoxicity is extensively identified contained in the trade, from a really fascinating invention patent that I dug out and supplies wonderful background info, it’s rather a lot, nevertheless it provides us nice particulars as to the extent of GO utilization and influence on well being:

Hey, youngsters, PEGylation is unhealthy for you!

“The in vitro research demonstrated concentration-dependent toxicity. The very best focus (100 μg/mL) of non-PEGylated rGO had a decrease poisonous affect on cell viability in major cultures of astrocytes and rat mind endothelial cells, whereas PEGylated rGO induced deleterious results and cell dying. We assessed hippocampal BBB integrity in vivo by evaluating astrocyte activation and the expression of the endothelial tight and adherens junctions proteins. From 1 h to 7 days post-rGO-PEG systemic injection, a notable and progressive down-regulation of protein markers of astrocytes (GFAP, connexin-43), the endothelial tight (occludin), and adherens (β-catenin) junctions and basal lamina (laminin) had been noticed. The formation of intracellular reactive oxygen species demonstrated by will increase within the enzymatic antioxidant system within the PEGylated rGO samples was indicative of oxidative stress-mediated harm. Underneath the experimental circumstances and design of the current examine the PEGylation of rGO didn’t enhance interplay with elements of the blood-brain barrier. In distinction, the attachment of PEG to rGO induced deleterious results as compared with the results attributable to non-PEGylated rGO.”

Biocompatible graphene quantum dots for drug supply and bioimaging purposes – United States Patent 9642815


On this work we’ve focused two points of GQDs, Measurement and ROS to cut back their cytotoxicity. Small dimension can harm cell organelles and manufacturing of ROS (reactive oxygen species) can hamper cell equipment in a number of methods. We have now proven that cytotoxicity may be considerably diminished by embedding GQDs contained in the PEG matrix reasonably than creating a skinny shell round every GQD. Skinny PEG shell round GQD can management ROS manufacturing however can not circumvent the toxicity on account of small dimension. Thus it was important to resolve each the problems. We have now used a easy electrochemical methodology (12 h at room temperature) for synthesizing GQDs and embedded them in PEG matrix through a easy one step hydrothermal response (24 h at 160° C.) involving solely GQDs, PEG, and deionized water. The P-GQDs shaped after hydrothermal response present nanoparticles of diameter of ˜80-100 nm containing GQDs entrapped in PEG matrix. MTT assay confirmed vital 60% cells viability at a really excessive focus of 5.5 mg/mL of P-GQDs in comparison with 10-15% viability for C-GQD and H-GQD. ROS manufacturing by P-GQDs was least in comparison with C-GQD and H-GQD in cell free and intracellular ROS assay suggesting involvement of ROS in cytotoxicity. On this work we’ve solved the problem of cytotoxicity on account of ‘small dimension’ and ‘ROS technology’ with out compromising with fluorescence properties of GQDs. P-GQDs was used for bioimaging and drug supply in HeLa cells. Briefly we are able to acquire biocompatible P-GQDs in very quick span of time with minimal use of hazardous chemical compounds and easy methodology.


A quantum dot is a semiconductor nanostructure that confines the movement of conduction band electrons, valence band holes, or excitons in all three spatial instructions. Quantum dots (QDs) are historically chalcogenides (selenides or sulfides) of metals like cadmium or zinc (CdSe or ZnS), which vary from 2 to 10 nanometers in diameter.

QDs have distinctive optical and digital properties reminiscent of size-tunable gentle emission, slender and symmetric emission spectra, and broad absorption spectra that allow simultaneous excitation of a number of fluorescence. Furthermore, QDs are immune to picture bleaching than natural dyes and fluorescent proteins. These properties are nicely fitted to dynamic imaging on the single-molecule stage and for multiplexed biomedical diagnostics at ultrahigh sensitivity.

Nonetheless, for in vivo and medical imaging, the potential toxicity of QDs stays a significant concern. The poisonous nature of cadmium-containing QDs is not an element for in vitro diagnostics, since emergent use of fluorescent QDs for molecular diagnostics and pathology is a vital and clinically related software for semiconductor QDs. (Kairdolf. B. et al., Annual Rev. of Analytical Chem. Vol. 6: 143-162.)

In prevalent apply, the usage of carbon nanoparticles in synthesis of quantum dots, have emerged as a brand new class of quantum dot-like fluorescent nanomaterials. Carbon nanoparticles are used since their particle dimension may be managed between 3-20 nm. Carbon atoms linked in hexagonal shapes, whereby every carbon atom is covalently bonded to a few different carbon atoms to kind graphene sheets. Graphene has the identical construction of carbon atoms linked in hexagonal shapes to kind carbon nanotubes, however graphene is flat reasonably than cylindrical.

Graphene quantum dots (GQDs) are used as fluorophores for bioimaging, owing to their physicochemical properties together with tunable photoluminescence, wonderful photostability, and biocompatibility. GQDs normally lower than 50 nm in dimension have been reported to have wonderful fluorescent properties. As a result of luminescence stability, nanosecond lifetime, biocompatibility, low toxicity, and excessive water solubility, GQDs are demonstrated to be wonderful probes for top distinction bioimaging and bio sensing purposes.

It’s actually excellent news that it’s develop into a meme subject!

References could also be made to prior artwork paperwork for strategies of synthesizing GQDs utilizing electrochemical processes, hydrothermal strategies and the modified Hummers course of for graphene oxide synthesis and cytotoxicity assays to find out the mobile uptake of the resultant GQDs shaped by these processes.

US patent publication, US 2013/0175182 supplies a course of for the transformation of single walled, double walled or multi walled carbon nanotubes to nanoribbons composed of few layers of graphene by a two-step electrochemical course of. The method includes oxidizing dispersed carbon nanotubes (CNT) to acquire CNT oxide and additional lowering it to kind graphene layers.

In analysis publication, Chem. Commun, 2011, 6858-6860, Zhu et al, describe a technique of GQD preparation whereby modified Hummers methodology is used for graphene oxide synthesis and hydrothermal methodology for GQD synthesis to acquire GQDs of particle dimension of 5.3 nm. At concentrations of two.6 mg/ml, cell viability of 80% is noticed.

Additional Jianhua Shen et al. in New J. Chem., 2012, 36, 97-101 reported one-pot hydrothermal response for preparation of graphene quantum dots surface-passivated by polyethylene glycol (GQDs-PEG) and their photoelectric conversion underneath near-infrared gentle, utilizing small graphene oxide (GO) sheets and polyethylene glycol (PEG) as beginning supplies.

Juan Peng et al. (Nano Lett., 2012, 12 (2), pp 844-49) describes the acid remedy and chemical exfoliation of carbon fibers, to supply GQDs within the dimension vary of 1-4 nm. The publication supplies that the GQDs derived haven’t any toxicity at concentrations of 0.05 mg/ml. Nonetheless, the cytotoxicity of GQDs at larger ranges is unaccounted.

Chang Ming Li et al., (J. Mater. Chem., 2012, 8764-66) present a technique to develop graphene quantum dots (GQDs) from XC-72 carbon black by chemical oxidation, nevertheless toxicity assays verify most cell viability at concentrations of 0.1 mg/ml.

The toxicity of GQDs is attributed to their dimension, since small sized GQDs work together with numerous proteins and organelles contained in the cell and disrupt mobile processes. One more reason for the toxicity is their capability to generate extra reactive oxygen species (ROS). Polymers, particularly PEG coating has been used within the literature to lower the toxicity of GQDs. Nonetheless, even after polymer coating the cell viability at larger concentrations (>1 mg/ml) is low. In all probability as a result of regardless that the ROS manufacturing is lowered by the polymer shell coating, the dimensions of the GQDs after coating nonetheless stays small (sub 50 nm) and are nonetheless within the dimension vary that may work together with intracellular proteins and organelles.

Within the following analysis publications, references could also be made to PEGylation of carbon nanoparticles and the cell viability decided at concentrations of 1 mg/ml or lesser than that.

Bhunia et al., (Scientific Experiences, 2013, 3:1473) describe carbon nanoparticles (FCN) that are polymer coated with PEG and the dosage dependent mobile toxicity of those fluorescent nanoparticles. At 1 mg/ml focus of the FCN-PEG composition, 55-60% cell viability is noticed.

Zhuang Liu et al., (J. Am. Chem. Soc., 2008, 130 (33), pp 10876-10877) describe pegylated nano-graphene oxide (NGO-PEG) of dimension 5-50 nm for supply of water insoluble most cancers medication produced by Hummers methodology.

Omid Akhavan et al., (J. Materials. Chem., 2012, Vol. 22, 20626-33) describes unhazardous concentrations of pegylated graphene nanoribbons for selective most cancers cell imaging and photothermal remedy. At concentrations of 1 mg/ml of the composition. 28% cell viability was obtained.

Additional Lay C L et al. (Nanotechnology. 2010 Feb. 10; 21(6):065101) experiences supply of paclitaxel by bodily loading onto poly (ethylene glycol) (PEG)-graft-carbon nanotubes for potent most cancers therapeutics.

Toxicity assays of GQDs synthesized by strategies of the above prior arts report minimal cell viability at GQDs concentrations of 1 mg/ml, and lesser than that, thus posing limitations in mobile imaging purposes. Nonetheless, to comprehend biomedical purposes of GQDs, low toxicity of the GQDS at larger concentrations is desired for mobile imaging.

With a view to supply graphene quantum dots (GQDs) with decreased cytotoxicity ranges at larger concentrations i.e. better than 1 mg/ml, the current inventors have supplied a biocompatible composition of a number of graphene quantum dots (GQDs) in a nanosized polymer matrix of polyethylene glycol which is bigger in comparison with small sized GQDs as noticed within the prior artwork. The PEG matrix aids in lowering the reactive oxygen radicals (ROS) generated by the GQD floor whereas retaining the small GQDs contained in the matrix; thus, additionally lowering their undesirable interactions with mobile proteins and organelles.

In the meantime, these nutjobs need to use it to deal with bone most cancers in youngsters!

Or how about:

Graphene quantum dots, their composites and preparation of the identical

United States Patent 9926202


Procedures for the synthesis of zero dimension GQDs primarily based on exfoliation/discount of floor passivated functionalized graphite oxide (f-GO PEG) are described. The synthesis procedures can embody exfoliation/discount f-GO PEG in presence of hydrogen fuel, utilizing targeted photo voltaic radiation and underneath vacuum.

Graphene nanoribbons tackle this downside of single layer graphene, nevertheless, extra just lately, focus has been on one other carbon nanostructure known as graphene quantum dots (GQDs) or carbon quantum dots (CQD) (often known as graphene quantum discs). GQDs present very fascinating photoluminescence properties, as the dimensions and form of the GQDs may be tuned to have desired band hole and emission properties. Furthermore, GQDs have fascinating traits, for instance, excessive floor space, bigger diameter, higher floor grafting utilizing the π-π conjugated community or floor teams and different particular bodily properties as a result of construction of graphene. Since many of the carbon nanomaterials together with GQDs are biocompatible and unhazardous, GQDs can advantageously be utilized in organic purposes for instance, picture scanning and sensing, drug supply and most cancers remedy. The photoluminescence properties of GQDs are helpful for photovoltaic purposes too because it has been theoretically proved that the power hole in GQDs may be tuned through the use of electrostatic potentials.

The band hole of a GQD will depend on its dimension and form. With present expertise it’s attainable to chop graphene in to fascinating dimension and form kinds. Because the variety of atoms will increase, the power hole in nearly all of the power spectra of GQDs decreases monotonously. Within the case of GQDs, together with dimension and form, the sting kind performs an essential function in digital, magnetic and optical properties.


This a part of the article isn’t absolutely substantiated with third half peer-reviewed proof, however with a few of my very own logic and observations, be happy to arbiter for your self:

The graphene nano-ribbons talked about above, when you payed consideration, are probably what La Quinta Columna and others observed on their microscopes. Both that or carbon nanotubes, that are about the identical factor, however in 3D.

Sinopeg claims it really works with US scientists and collaborates with Chinese language Academy. Similar to Invoice Gates, who is without doubt one of the only a few international members of the Academia there, as I revealed final 12 months.
It’s nearly unconceivable that Gates didn’t know of those PEGs and didn’t need to shield the key from most people.
Sharing the manufacturing and the patents with the entire world would’ve nearly definitely result in info leaks, and that’s what apprehensive Gates greater than cash leaks, that are his final concern proper now, I believe.


Ah, and in case you need to go even deeper into the science:
