@Metal-Brain You don't seem to know the uses of copper in semiconductor chip manufacturers, copper is now used for interconnect lines, where a previous problem had to be solved, copper migrating out of the line shorting out other stuff on the chip. That is solved and now copper is a main line metal in that industry.
Then there is electrical wiring, most now aluminum but copper is a better electrical conductor but if you want the best conduction you use copper or silver which is a bit more expensive....

@Metal-Brain Copper would have biological effects if a tiny needle made of copper is used as a neuron connector.
That doesn't reduce the usefulness of copper in electronics and wiring and as an alloy for metallurgy.

Why are you ignoring the human brain in regards to graphene?
Graphene-based neurotechnologies for advanced neural interfaces
Researchers at Georgia State University and Emory University have developed an intranasal influenza vaccine using recombinant hemagglutinin (HA), a protein found on the surface of influenza viruses, as the antigen component of the vaccine.
They also created a two-dimensional nanomaterial (polyethyleneimine-functionalized graphene oxide nanoparticles) and found that it displayed potent adjuvant (immunoenhancing) effects on influenza vaccines delivered intranasally.
