Green Synthesis and Characterization of Silver Nanoparticles and Evaluation of their Antibacterial Activity using Elettaria Cardamom Seeds

Abstract

In present we have been producing metallic nanoparticles with toxic and harmful chemicals which are more dangerous to environment. Therefore there is a need to develop environment friendly synthesis techniques without using toxic chemicals. In this work a simple and green/eco-friendly/chemical free biosynthesis of silver nanoparticles using C seed extract as reducing agents was prepared. Nanoparticles were characterized by UV-vis absorbance spectroscopy, XRD and SEM measurements. The metal ions reduction occurs very rapidly, and the reduction of Ag ions will be completed within 4 hours. The synthesized silver Nanoparticle distinct monodispersity as they show particle size between the ranges of 30-80 nm. The experimental study confirmed the formation of highly crystalline nanoparticles with uniform shape. Further, the antibacterial activity against the Bacillus subtilis was also evaluated for Elettaria cardamom seeds extract assisted silver nanoparticles and the later found to exhibit significant activity.
