Nanotoxicology deals with the new perception regarding nanotechnology i.e. risk and hazards associated
with nanoscale materials. Although, nanotechnology is playing significant role in modern advancements from cell
phones to medicines, yet it is necessary to consider their negative part as well that could be dangerous if not given
proper attention. It is not certain that nanotechnology will essentially exert toxic effects since at present only few
reports are available on their toxic effects and most of them are controversial. In this review we have summarized
the advances in nanotechnology, their applications and, most importantly their safety issues that are often overlooked.
However combined efforts are advocated to develop promising regulatory and ethical guidelines to control
production, use and disposal of nanomaterials that will be safe to human health, environment and other living organisms.
