Synthesis Of Silver Nanoparticles Using By Gum Arabic Based Hydrogel

Abstract

Different researchers have been working to synthesis silver nanoparticles by biological method because this method takes less time, low cost and one step method. Biodegradable material such as gum, bacteria, fungus etc. are used to synthesis silver nanoparticles and organic molecules which are present in biodegradable material, provides stability to silver nanoparticles. Biological method is used to synthesis of silver nanoparticles in this research. Gum Arabic Polyacrylamide Fumaric Acid (GAPAAFA) based hydrogel,used to synthesis silver nanoparticles. GAPAAFA hydrogel is taken into grey solution that contains silver particles that formed from silver nitrate and borax and after three hours, grey solution changes into brownish/yellow silver nanoparticles. GAPAAFA acts as stabilizing and capping agent. Synthesis of silver nanoparticles confirmed by the following method such as Ultra Violet-Visible Spectroscopy (UV-VIS),Thermo-Gravimetric Analysis(TGA),Dynamic Light Scattering(DLS),  Zeta potential and effect on Escherichia coli and Bacillus subtilis.
