I like how we all now know that microplastics and PFAS seriously contaminate our water sources, but there's no real thought about things like nanotubes doing the same thing. Wonder what consuming carbon nanotubes might do to us.
Unless there is something special about carbon chains, ingesting them is probably like ingesting activated carbon. Ingested activated carbon is part of a treatment for poison. https://en.m.wikipedia.org/wiki/Activated_carbon
Well yeah it's a whole different shape (very pointy and can penetrate or shred cell membranes), and the electrical properties of graphene can be pretty weird.
Not the same but some people have experimented with C60 spheres. Apparently it is either very good or it increases ROS reactive oxygen species depending on who you ask and how it is prepared
