These days, nanoparticles are being considered as nano-antibiotics because of their execution of antimicrobial activities towards a broad range of microbes. Nanoparticles are used in industrial products, health, food, space, and cosmetics;thus, researchers need for a green, ecofriendly, and low-cost approach to synthesize it. Green synthesis is such an approach of synthesizing NPs using microorganisms and plants, which is free of additional impurities. We used Mimusops elengi Linn. raw fruit extract in water to reduce the silver nitrate salt to produce silver NPs. The samples were characterized using various instrumental techniques. Broadband known as Surface Plasmon Resonance found near 450 nm in the absorption spectrum shows the formation of Ag NPs. NPs with average hydrodynamic diameters in the ranges 20-300 nm were detected from DLS study having negative zeta potential value (varies between - 25.8 to 15.8 mV), which suggests that as NPs surface is charged, it provides colloidal stability to the NPs in a liquid medium. FTIR study reveals that an increase in the intensity of some of the vibrational band with NP-content is due to the adsorption of some molecules on the surface of NPs. XRD pattern shows that NPs have an fcc structure. Samples were tested to have capabilities to kill both bacteria and fungi.
