ABSTRACT

 

Nanotechnology is a rapidly growing science of producing and utilizing nano particles. Synthesis of nanoparticles takes place for many applications in various field of science, technology, medicine, colloid technology, diagnostics, drug delivery, health impacts, food, personal care applications etc.. Their unique size make them more chemically reactive and more bioactive. Nanosilver is one of the most used nanomaterial in many consumer products predominantly as a bactericide in medicine, eating utensils, crockery, food containers, electronic gadgets and as a disinfectant for water and human infection. Along with its good antimicrobial activity it is also reported to be toxic to beneficial bacteria. Evidences also show that silver nanoparticles are highly toxic to mammalian cells, brain cells, liver cells, stemcells. Prolonged exposure to silver causes skin diseases also. These nano antimicrobials are threat to aquatic life also, when released in waste stream. The aim of this paper is to give an over view and analyze various toxic effects of silver or silver nanoparticle on human health and environment.
