ABSTRACT
Nanotechnology has an important part in our daily life. Nanomaterials are used in different fields like textiles, medical devices, drugs, cosmetics, and various other things. Nanoparticles (NPs) penetrate into the human body through various channels. The size and surface of NPs play an important role in determining the toxicity. In this chapter, we tried to find out the adverse influence of NPs on human health and the environment.
