BIOMIMETIC SYNTHESIS AND CHARACTERIZATION OF SILVER NANOPARTICLES (AGNPS) USING VINCA ROSEA AQUEOUS EXTRACT

Abstract

Biomimetic route for the synthesis of silver nanopartilces with using biological source play a very important role in nanotechnology without any harmful chemical. The present study deals with the synthesis of silver nanopartilces by treating silver nitrate with aqueous extract Vinca rosea at room temperature. The
effect of the Vinica rosea aqueous extract on the formation of silver nanopartilces was characterized by UVvisible spectroscopy (UV-Vis), X-ray Diffraction Spectrum (XRD), Scanning Electron Microscopy (SEM) and Energy Dispersive X-ray Analysis (EDX). The UV spectra results show a strong resonance centre and surface
of silver nanopartilces (AgNPs) at 461 nm. XRD and SEM studies revealed that the synthesized AgNPs shows spherical in shape with average particles size around 30- 70 nm.
