Abstract

In order to study the green creation of silver nanoparticles (AgNPs) by decreasing the Ag+ ions in a silver nitrate solution, green tea plant extract was utilized. The generated AgNPs were examined by UV-Vis spectroscopy, field emission scanning electron microscopy, and Fourier transform infrared spectroscopy (FTIR). The produced AgNPs were 685 nm in size, spherical in shape, polydispersed in nature, and exhibited a maximum absorbance at 416 nm. Escherichia coli and Staphylococcus were successfully combatted by the AgNPs.
