In the right size, the GO nano particles can agglomerate in cell tissues which perhaps can be used to attempt to localize transport of the vaccine particles to target sites restricted to the immediate location of the injection site, either for safety or to maintain a concentration to optimize the immune response to the vaccine.
Nano engineering is very cool stuff, but it's not well understood how nano particles interact in the human body or how long they are retained so the long term effects are not well understood.
Strange, unexpected and unpredicted things happen with nano particles all the time and he bioactivity can change radically depending upon the size of particle once you go below a certain threshold. This can be problematic unless you can control the size distribution to an adequately narrow spectrum
Frankly, I'd rather take Ivermectine or HCQ as a preventative for Wuhan virus.
"...You can even graft on groups that make some sites of the graphene nano particle hydrophyllic and some hydrophobic."
Great, so you can induce primary structure (at least) onto the sheets; better hope you've modeled the conformational space well, or *thoroughly* tested it, or some unforeseen biological condition will have it changing shape and therefore behaviour/effect on the body without warning.
Sheesh, even proteins, while being created, need helper proteins to help guide/form them into the active, desired conformation, it's not just a matter of the raw amino acid sequence.
Oh, see also "prions". Wondering about the rumors of one of the doctors saying the beta sheet in the spike protein would induce prion formation in the brain. I don't necessarily think that's been demonstrated yet, but would the graphene oxide have the ability to denature various proteins along the way? Yikes.
Hard to believe they would do that, but my ability to believe the unbelievable has been expanded in the last few years
