ABSTRACT

Discoveries in the past decade in the field of medicine along with Nano-Engineering principles explored a various new dimensions which attributed significantly in various ways. Currently there is a growing need for biomimetic synthesis of nanoparticles by using biological sources without using any harmful chemicals plays a very important role. The present study deals with the synthesis of silver nanoparticles by treating silver nitrate with aqueous extract of Emblica officinalis (Gooseberry) plant at room temperature and its effect on formation of AgNPs. They were subjected for to various characterization techniques to analyse their physical and chemical prosperities like size, shape, crystallinity, fractal dimensions, pore size & surface area were done. Finally biopotentiality of synthesized AgNPs was done against selected gram positive and gram negative bacterial strains and their zone of inhibition was measured & recorded. The present findings may be recommended for production of antibiotics & can be applied as antimicrobial agent.
