GREEN SYNTHESIS OF SILVER NANOPARTICLES USING Adhatoda vasica METHANOLIC EXTRACT AND ITS BIOLOGICAL ACTIVITIES
Journal Title: Journal of Atoms and Molecules - Year 2012, Vol 2, Issue 4
Abstract
There is an increasing commercial demand for nanoparticles due to their wide applicability in various areas such as electronics, catalysis, chemistry, energy, and medicine. Metallic nanoparticles are traditionally synthesized by wet chemical techniques, where the chemicals used are quite often toxic and flammable. In this work, we describe a cost effective and environment friendly technique for green synthesis of silver nanoparticles from 1mM AgNO3 solution through the Methanolic extract of Adhatoda vasica as reducing as well as capping agent. Nanoparticles were characterized using UV–Vis absorption spectrophotometry, FTIR and SEM. SEM analysis showed the average particle size of 15-20nm as well as spherical to oval in shape. The synthesized nanoparticles show high DPPD free radical scavenging activity and reducing power activity. Further these biologically synthesized nanoparticles were found to be an anti diabetic agent and highly toxic against different human pathogens.
