Abstract
Green synthesis of silver nanoparticles (Ag NPs) using Prunus×yedoensis leaf extract was studied. Color changes, ultraviolet–visible spectra (436nm), X-ray diffraction peaks (2θ=39.26, 45.54, 65.12, and 79.21) and Fourier transform infrared spectroscopy (FT-IR) confirmed the presence of Ag NPs. Transmission electron microscopy shows that the nanoparticles are mostly spherical and oval in shape, with an average particle size of 20 to 70nm. The phytoconstituents present in the leaf extract could be responsible for the reduction of Ag+ ions. The synthesized Ag NPs (30μg) show a 18 and 20mm zone of inhibition against skin pathogens Propionibacterium acnes and Staphylococcus epidermidis compared with commercial Ag NPs.
