Abstract

Due to their environmentally friendly manufacturing process, silver nanoparticles (AgNPs) have attracted a lot of attention from chemists and researchers in recent years. The antibacterial activity of the synthesized AgNPs was thoroughly analyzed and characterized. For the purpose of characterization, transmission electron microscopy (TEM), scanning electron microscopy (SEM), and Fourier transform infrared spectroscopy (FTIR) were utilized. The ethanol extract's UV analysis wavelengths were identified as

428 nm and 414 nm, respectively. The produced AgNPs had significantly greater antibacterial activity against a variety of bacteria, including E. coli, B. subtilis, S. aureus, K. pneumoniae, when compared to AgNO3 and untreated extracts.
