What are the Possible Dangers of Nanotechnology?
Nanotechnology is a branch of science that deals with particles 1-100 nanometers in size. Experts believe possible dangers of nanotechnology lie in how these tiny particles might interact with the environment, and more importantly, with the human body. Billions of dollars are being spent to incorporate nanoparticles into products that are already being marketed to the public; when this investment is compared to the the comparatively scant research into nanotech health issues, some scientists become concerned. Experts say the issue is that elements encountered at the nanoscale behave differently than their larger counterparts. As an example, graphite’s properties are well known and it holds specific position in toxicology guidelines. Nobel winning physicist Richard Smalley of Rice University discovered carbon nanotubes and fullerenes (buckyballs) — nanoparticles of carbon — which are legally categorized as graphite, yet they behave in ways unlike graphite making the classification a pot
