A novel route for large-scale synthesis silver nanoparticles using Uncaria tomentosa leaves extract: Antibacterial activity

The present study deals with rapid and large-scale synthesis of silver nanoparticles (AgNPs) by U. tomentosa leaves aqueous extract at ambient temperature. Crystal growth of silver nanoparticles by this green route was formed within 5min at room temperature. Synthesized AgNPs were characterized by Ultra-violet visible spectrophotometer (UV-vis), Fourier transform infrared spectroscopy (FT-IR), Transmission electron microscopy (TEM) and X-ray diffraction (XRD). Silver nanoparticles synthesized by green route showed better antibacterial activity. Copyright © 2018 VBRI Press.
