Research conducted on certain breast cancer cells suggests that nanoparticles could damage DNA and lead to cancer. The study, performed at the University of Massachusetts, examined how two types of nanoparticles could cause DNA damage in the tissue. Unfortunately one of the main problems in the nanotech area is that there's still not nearly enough information known about how harmful (or harmless) materials could be at the nanoscale.
