Green synthesis of silver nanoparticles using Grevillea robusta

Silver nanoparticles have been intensely investigated due to their excellent unique properties and applications. The present work has been conducted with silver nanoparticles synthesis usinggrevillea robustaleaf extract. The morphology of sliver nanoparticles was analyzed by transmission electron microscopy (TEM), scanning electron microscopy (SEM) and particle size analyzer (PSA). The physiochemical analysis of nanoparticles was done by X-ray powder diffraction (XRD), Fourier-transform infrared spectroscopy (FTIR) and UV-Vis spectroscopy. The silver nanoparticles showed antibacterial activities against both gram positive (Micrococcus luteus) and gram negative (Pseudomonas alkaligenes) microorganism. The results confirmed this method is ecofriendly, cost effective, and nontoxic for the synthesis of Ag nanoparticles.
