Whatever you do don’t look up:
carbon nanotubes
silicon dioxide nanoparticles
gold nanoparticles under radio frequency excitation
tungsten oxide nanoparticles
Nah, it doesn’t take much and gold nanoparticles are cheap. It really doesn’t take much. Saw an article a while back where they injected AuNPs into a tumor and pumped with RF(13.56MHz I think). Basically cooks the tumor.
Well, shit. I now have a new phobia- breathing in tiny spikes
