Materials by changing their size from normal to nanometer range shows a great change in their physicochemical properties primarily due to their small size and large specific surface area. A number of techniques have been reported for the preparation of metallic nanoparticles but there is a great need to develop environmentally benign nanoparticle synthesis processes without use of toxic chemicals. Therefore use of biological systems for preparation of nanoparticle is considered as a best solution where use of toxic chemicals and harsh preparation methods can be avoided. Silver nanoparticles can be prepared by bioreduction process using bacteria, actinomycetes and fungi etc very efficiently. The silver nanoparticles formed are having efficient antimicrobial activity
