In this report a simple and eco-friendly biosynthesis of silver nanoparticles using Pomegranate peel extract as the reducing agent from 1 mM AgNO3 had been investigated. The formation of silver nanoparticles was characterized by UV-Vis spectrum, Fourier Transform Infrared Spectroscopy (FT-IR) and Scanning Electron Microscopic (SEM) analysis. The UV-Vis spectra results show a strong resonance centered on the surface of silver nanoparticles (AgNPs) at 371 nm. The Fourier Transformation Infrared Spectroscopy spectral study demonstrates pomegranate peel extract acted as the reducing agent. The scanning electron microscopic (SEM) analysis shows nanoparticles with the average particles size ranges about 5-50 nm. Further the antibacterial activity of AgNPs was evaluated against Staphylococcus aureus, Pseudomonas aeruginosa and Escherichia coli pathogens. This route is rapid, simple, without any hazardous chemicals as reducing or stabilizing agents and economical to synthesize AgNPs.
