ABSTRACT

 

Today the “Green nanoparticle” synthesis has been achieved using environmentally acceptable solvent systems and eco-friendly reducing and capping agents. The present study investigated the synthesis of silver nanoparticle using pomegranate fruit extract as reducing agent to synthesize silver nanoparticles. The fruit peel extract itself was used for phytochemical screening to find out phytochemical constituents present in it. Peel extract of pomegranate was challenged with silver nitrate for the production of silver nanoparticles. The reaction process was simple for the formation of highly stable silver at room temperature by using the biowaste of the fruit. The formation of nanosized silver particles was confined by its characteristic surface Plasmon adsorption peak at around 440 nm in UV-Vis spectra. The morphology and crystalline nature, were characterized by Scanning Electron Microscopy (SEM). Antimicrobial property was studied against Escherichia coli whereas antifungal property was studied against Aspergillus niger. The minimum inhibitory concentration of the produced silver nanoparticles was studied against the organisms. The use of green nanotechnology appears to be a cost-effective, simpler to synthesize, ecofriendly and an easy alternative for the convential methods.
