Abstract

BIOSYNTHESIS OF SILVER NANOPARTICLES BY DATURA METAL FLOWER EXTRACT

V.Bharathi, S. Gomathi , A.Shanmuga Priya and G.Gayathri

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. In this work deals with the synthesis and characterization of silver nanoparticles using Datura metal flower. Synthesized nanoparticles were characterized by using UV–Vis absorption spectroscopy, FTIR, and SEM analysis. The reaction mixture turned to brownish gray color after 5 hrs of incubation and exhibits an absorbance peak around 450 nm characteristic of Ag nanoparticle. Scanning electron microscopy (SEM) analysis showed silver nanoparticles was pure and polydispersed and the size were ranging from 10-40 nm. The approach of green synthesis seems to be cost efficient, eco-friendly and easy alternative to conventional methods of silver nanoparticles synthesis.

Keywords: FTIR, nanoparticle, UV–Vis absorption spectroscopy.
