Plant Extract Synthesized Silver Nanoparticles and their Antimicrobial Activity

Abstract

Silver nanoparticles have many medical and industrial applications. The nanoparticles are usually synthesized by chemical and physical approaches. However, major disadvantages of both approaches are non eco-friendly and costly synthesis processes. Therefore, biological approach has currently become an alternative and holds interest for many researchers. Nevertheless, biological mechanism of silver nanoparticle synthesis remains unclear. This review provides information on how to synthesize silver nanoparticles by plant extract, effects of the synthesis parameters, synthesis mechanism and some applications of silver nanoparticles in antimicrobial activities.
