Abstract

In the present study, we report a simple, rapid, cost-effective approach for the white synthesis of silver nanoparticles (AgNPs) using Capra aegagrus hircus milk. The formation of AgNPs was visually examined and further investigated using UV–visible spectrophotometer, transmission electron microscopy, scanning electron microscopy with energy dispersive X-ray, Fourier infrared spectroscopy, and X-ray diffractometer. Crystalline lattice indices of AgNPs were performed using the XRD analysis. The diffraction peaks at 2θ values of 37.7°, 46.1°, 67.4°, and 76.84° corresponding to lattice planes (111), (200), (220), and (311), respectively. The obtained AgNPs were spherical in shape with the size between 5 and 50 nm. The antibacterial activity of AgNPs against Klebsiella sp. (Accession Number: KC899845), and Staphylococcus sp. (Accession Number: KC688883) were evaluated by means of cell growth.
