A review on plant mediated synthesis of silver nanoparticles and their antimicrobial activity against various pathogenic bacteria

Nanotechnology introduced the concept of nanoparticles, which exhibit unique and remarkably different properties from their bulk materials. Chemical methods are widely used among various strategies of synthesizing nanoparticles. Green synthesis is utilized as a cost effective and environmentally friendly alternative to the chemical method of synthesizing nanoparticles. Plant mediated synthesis of the nanoparticles is recognized as most promising green synthesis method and researchers have paid closer attention to the green synthesis of silver nanoparticles due to their remarkable antimicrobial activity. The review focus on the recent studies and present the methodology used in bio-reduction of silver nitrate solution using plant extracts, methods used in characterization of synthesized nanoparticles, various antibacterial assays conducted and also giving a brief overview of the results obtained from them.
