RE:RE:Does HC know about thisThere have been no testing on the effects on GO or graphene on the human lung by any manufacturing companies hence the HC moratorium on graphene and graphene coating masks. Until it's has gone through the third phase of human trials nothing is getting approved no matter what ignorant investors try to post and tell the world.
Back in 2012, graphene and graphene nanoparticles have been identified as hazardous to the oxygen blood layer in the lungs similiar to coal dust and asbestoes

Graphene in any face mask is dead.
Move on graphene has so many other opportunities not being invasive to the human body.
