BIO-SYNTHESIS OF SILVER NANOPARTICLES

e continuously being synthesized so by bringing about reduction of certain precursors using strong chemical reducing agents. Often chemical synthesis method leads to presence of some of the toxic chemical absorbed on the surface that may have adverse effect in the medical applications.These reducing agents have been found to be possessing lot much of toxic potential and thereby health hazardous. Therefore present article reviews the different methods used for synthesis silver nanoparticles. Thus silver nanoparticles have been continuously synthesize from different materials using green reducing agents which have biological origin and efficient both in terms of economy and energy. Biological methods for synthesis have thus paved way for the “greener synthesis” of nanoparticles and these have proven to be better methods due to slower kinetics. Green synthesis provides advancement over chemical and physical method as it is cost effective, eco-friendly, easily scaled up for large scale synthesis
