Nanoparticles have been a key part of numerous recent technological advances. Biofuels, solar cells, medical imaging systems and even sunscreen - there's virtually no field of science or technology that they couldn't potentially transform. There are concerns however, about the risks posed by the countless tiny particles of materials such as silver, gold and titanium dioxide that are now entering our environment and our bodies, but a recent University of Oregon study suggests that if not completely harmless, nanoparticles are at least nothing new. In fact, it states, humans have been exposed to them for millennia... Continue Reading Study shows that we've been exposed to nanoparticles for thousands of years
