A novel green method was developed to create pure, safe, and stable silver nanoparticles (AgNPs) using Trema orientalis (L.) leaf extract as a reducing stabilizing agent evaluated its antibacterial activity. UV-vis spectroscopy indicated the biogenesis of AgNPs based on absorbance in range 400–500 nm. The Fourier transform infrared (FTIR) revealed that flavonoids play crucial role synthesis stability AgNPs, serving primary phytoconstituents involved. were spherical, crystalline nature. size ranged from 14.04–34.38 nm determined by transmission electron microscopy (TEM). For phase determination structure, subjected X-ray diffraction (XRD). crystallinity percentage calculated 79.28%. investigation atomic force (AFM) measured average roughness, maximum height, valley depth AgNPs. mean surface roughness 12.054 well diffusion demonstrated activity against Staphylococcus aureus, resulting inhibition zones measuring 9 , 10 13 14 mm. These effects observed at concentrations 25 µg/mL, 50 75 100 respectively. minimum inhibitory concentration S. aureus 55.31 μg/ml. This work provides more sustainable efficient bacterial treatment.
