It is because of effectiveness in synthesis of the nanoparticles. This study has been designed for the synthesis of green silver nanoparticles also to study the antimicrobial activity. Methanol extracts of plant leaves was prepared using the maceration and were used for the synthesis of silver naoparticles. Bergenia ciliata silver nano particles found to be more effective against various pathogenic bacterial strain as compared to Bergenia ciliata extracts. The synthesized Bergenia ciliata silver nanoparticles showed increased antimicrobial activity. These results have supported greater advantage of use of bio-green methods for preparation of nanoparticles which have greater potential against antimicrobial activitiy.
