Directly related to your post on graphene oxide in the jab - which I sent to numerous friends.
Make your own carbon aerogel:

No, this one is not graphene but pyrolyzed phenol resorcinol.
Placing non-resorbable particles, including nanoparticles, into the body can be dangerous.
Example:
There is plenty of literature about drug addicts who crush up pills to inject. They can get lung and heart problems from the crospovidone particles used as disintegrants in tablets.
I can see this being made into thread to be woven like kevlar producing a stronger, lighter weight bullet resistant cloth. If set with epoxy or ceramic, could be very useful as hard armor.
