Green Synthesis of Silver Nanoparticles:Eco-Friendly and Antibacterial

Abstract

<span style="font-size: small;"><em>Nano world daily. In this paper the Lens culinaris seed extract was assessed for thegreen synthesis of</em><em> </em><em>silvernanoparticlesat temperature of 25</em><span style="font-family: Calibri;">◦</span><em>C. The nanoparticles were characterized using Inductively CoupledPlasma spectrometry (ICP), X-ray diffraction (XRD) and Transmission electron microscopy (TEM). Thenthe antimicrobial activities of these nanoparticles were investigated. P. aeruginosa and S aureus were</em><em> </em><em>used as representatives of Gram-negative and Gram-positive bacteria, respectively. Percentage conversion</em><em> </em><em>of metal ion to metal nanoparticles were more than 95% after 60 days of the reaction. XRD was used to</em><em> </em><em>confirm the crystalline nature of the particles. Silver nanoparticles were mostly spherical with range in</em><em> </em><em>size from 5-25 nm. Ag nanoparticles synthesized with extract were exhibited a strong antibacterial activity</em><em> </em><em>against bothP.aeruginosa and S.aureus.This process is completely green and eco-friendly compatible.</em></span>
