Green Biosynthesis of Silver Nanoparticles Using Aqueous Extract of citrus sinensis Peel

Abstract

Silver nanoparticles (AgNP's) biosynthesis was accomplished using hot aqueousextract of citrus sinensis peels as a simple, safe, low cost and ecofriendlyreducing agent for sliver nitrate ions. This procedure was carried out at 37 0C, thefirst indication of producing the AgNP's was changing the color of solution fromyellow to dark brownish which was confirmed by UV-VIS spectrum, XRD,EDXand SEM analysis. Obtained Ag nanoparticles were evaluated for their antimicrobialactivity against the gram-positive and gram-negative bacteria..This workproved the capability of plant mediated silver nanoparticle using the principles ofgreen chemistry as a promising candidate that alternate for physical and chemicalsynthesis.
