Study of nanotoxicity: Current need

Nanotechnology has potential to improve almost all aspect of human life. With the advent of nanotechnology a number of engineered nanoparticles have made their importance in our day to day life. But history has taught us that the development of every new technology is accompanied by risks. Hence it is highly required to study all possible risk factors associated with any technology. This article is a glimpse of the toxic effects of nanoparticles and emphasizes on detailed effects on nanoparticles on human health and environment.
