SYNTHESIS OF SILVER NANOPARTICLES USING PELTOPHORUM PTEROCARPUM FLOWER EXTRACT AND EVALUATION OF THEIR ANTIBACTERIAL ACTIVITY

Abstract

The current study manifested that the aqueous flower extract of Peltophorum pterocarpum contain bioactive compounds, is found to be responsible for bioreduction during the synthesis of silver nanoparticles The synthesis of silver nanoparticles occurred under the exposure of the flower extract to 1mM silver nitrate aqueous solution .During this process the complete reduction was observed nearly 48 hours at room temperature. During the incubation period the color change was observed .Synthesized silver nanoparticles were characterized by UV-Visible spectroscopy, FTIR were carried out to assess the formation of silver nanoparticles. The formation of Ag-NPs was confirmed by TEM, XPS and XRD studies. The synthesized Ag-NPs flower extract was carried out against the fish pathogenic microorganism by agar- well diffusion method. It exhibited good antibacterial activity. The effect of antibacterial activity depends upon the concentration of Ag-NPs.
