GREEN SYNTHESIS AND CHARACTERIZATION OF SILVER NANOPARTICLES FROM ALLAMANDA BLANCHETII A.DC., LEAVES EXTRACT AND THEIR ANTIMICROBIAL ACTIVITIES

Supriya S B, Navyashree H. T

Abstract

Nanoparticles are fundamental blocks of nanotechnology. An eco-friendly approach for green synthesis of nanoparticles using natural Plant extract is gaining a notable importance now a days. The present study deals with the synthesis of silver nanoparticles using Allamanda blanchetii A.DC. Leaf extract. The complete reduction of silver ions was observed after 48 hours of reaction at 30ºc under shaker condition. The formation of silver nanoparticles was confirmed by Uv – visible spectroscopy, XRD and SEM analysis. The antifungal evaluate against Aspergillus niger and Rhizopus stolonifer. The antibacterial activity evaluated against Escherichia coli and Bacillus subtillis.

Keywords
