Green Biosynthesis of Silver Nanoparticles Using Aqueous Extract of citrus

الملخص

Silver nanoparticles (AgNP's) biosynthesis was accomplished using hot aqueous extract of citrus sinensis peels as a simple, safe, low cost and ecofriendly reducing agent for sliver nitrate ions. This procedure was carried out at 37 ⁰C, the first indication of producing the AgNP's was changing the color of solution from yellow to dark brownish which was confirmed by UV-VIS spectrum, XRD,EDX and SEM analysis. Obtained Ag nanoparticles were evaluated for their antimicrobial activity against the gram-positive and gram-negative bacteria..This work proved the capability of plant mediated silver nanoparticle using the principles of green chemistry as a promising candidate that alternate for physical and chemical synthesis.
