Nanotechnology is the current boon of science to mankind. The enormous growth in nanotechnology has not spared any field and in particular it has engraved its success in the field of medicine. It is also important that one must be aware of the potential hazards of nanotechnology as it has grabbed a major position in the world of science and technology. The biological impacts of nanoparticles are dependent on size, chemical composition, surface structure, solubility, shape, and aggregation. These parameters can modify cellular uptake, protein binding, translocation from portal of entry to the target site, and the possibility of causing tissue injury. Effects of nanoparticles depend on the routes of exposure that include gastrointestinal tract, skin, lung, and systemic administration for diagnostic and therapeutic purposes. This review would talk in volumes about the potentially hazardous effects of nanotechnology.
