SILVER NANOPARTICLES EMBEDDED PAM/CMG HYDROGEL – IN-SITU GENERATION BY GREEN SYNTHESIS AND ITS ANTIMICROBIAL ACTIVITY

Abstract

Synthesis of silver nanoparticles using green chemistry process has become the prime focus of interest. This research article reports the in-situ generation of silver nanoparticles during copolymerization of polyacrylamide/carboxymethyl jargon crosslinked hydrogel through green route that is without using toxic reducing agents and solvents. The formation of silver nanoparticles was characterized by Ultraviolet-visible spectroscopy, Fourier transform infrared spectroscopy, scanning electron microscopy, Energy dispersive analysis of X-ray, transmission electron microscopy and X-ray diffraction methods.  All these methods confirmed the formation of Ag NPs during hydrogel synthesis. The silver nanoparticles produced in polyacrylamide/carboxymethyl guargum hydrogel matrix were also examined for antimicrobial activity against E.Coli.
