We have heard about the biotoxicity of graphene, a two-dimensional form of carbon that was embraced by both industry and biotech. Phosphorene is the new graphene, a nanomaterial showing far less toxicity to biological tissues and proving to be just as wondrous in terms of its conductivity (electrical and electrochemical properties), as well as its optical (photothermic and photodynamic) capabilities. Black phosphorus or phosphorene (pictured above) is already found in human bones, constituting 1% of human mass and thus making it a good substitute for graphene in biomedicine. Remember graphene oxide? BP may replace it in vax manufacturing ...
