Abstract

Abstract- Green synthesis is an emerging nanotechnological tool for medicines and nanotechnology. In green synthesis we used natural reducing agents to synthesize nanoparticles (in this case these are gold nanoparticles and silver nanoparticles). Conventionally, gold and silver nanoparticles are synthesized by wet chemical technique where toxic and/or flammable chemicals are used. The present study focus on a cost effective and safe technique to synthesize Gold and Silver nanoparticles by using leaves and bark of Ficus carica with aqueous solution of 1mM HAuCl4 and 1mM AgNO3 respectively. The leaves and bark were found to be a reducing agent as well as capping agent which can rapidly reduces auric ions (Au+ to Au0) and silver ions (Ag+ to Ag0). UV-VIS spectroscopy and Scanning Tunneling Microscopy (STM) were used to characterize Gold as well as Silver nanoparticles. Index Terms- Green technology, microwave irradiation, microscopy, spectroscopy, and Ficus carica.
