RE:RE:Zen Graphene is a game changeryour partially wrong, since when they get HC approval for Graphene sylver oxide Ink for PPE coating they will actually have sales... (it should be in the comming days/weeks)
Regarding NOVEL GRAPHENE-BASED POTENTIAL TREATMENT FOR BACTERIAL AND VIRAL INFECTIONS IN HUMANS, they are currently beginning level 2 clinical trial... and they already have preliminary toxicity results, which were probably done at first time to get HC approval for the Ink...
They have a proof of concept on a potential broad-spectrum solution for global infectious disease management, Gov all over the world have been able to approve a vaccine against Covid in less than a year, and ZEN comming out without something really really big for the world public health, do you really think it will take many years to bring this on the market? IMO
