PLANT-EXTRACT-ASSISTED GREEN SYNTHESIS OF SILVER NANOPARTICLES AND THEIR IMPORTANCE

Abstract

The present paper briefly describes the  biosynthesis of silver nanoparticles and  their application in different fields.  Biosynthesis is a novel way to synthesize  nanoparticles by using biological sources.  It is gaining much attention due to its cost  effective, eco friendly and large scale  production possibilities. Generally  physical, mechanical and chemical  methods are involved for the synthesis of  such important nanoparticles. But these  methods are very expensive and some 

methods involve harmful chemicals. With the aim of developing clean, nontoxic and  eco-friendly technologies, a wide range of  biological sources has been used for the  formation of nanoparticles. The  importance of this study includes a precise  and specific analysis of silver  nanoparticles from biological systems that  may support and revolutionize the art of  synthesis. Nanotechnology is a modern  field of science which plays a significant  role in day to day life aspects.
