چکیده

The present investigation was aimed to synthesis of silver nanoparticles (AgNPs) using Dodonaea viscosa (D.viscosa) leaf extract by an eco-friendly method. The leaf extract worked as bioreductant and stabilizer. The biosynthesized AgNPs was characterized by Ultraviolet visible (UV-vis) spectrophotometer, the leaf extract worked as reductant and stabilizer. The surface plasmon resonance (SPR) peak was observed at 440nm. Fourier Transmission Infrared Spectroscopy (FTIR) exhibited the various functional groups which, were used for capping of nanoparticles (NPs). Field Emission Scanning Electron Microscope (FESEM) and Transmission electron microscopy (TEM) analysis measured the size of the AgNPs ranged from 22.9 to 41.5nm. The X-ray Diffraction (XRD) pattern conformed the face centered cubic (fcc) crystalline structure of AgNPs. The bio-reduction of the silver ions in solution was monitored by Energy dispersive X-ray spectroscopy (EDX). The synthesized AgNPs showed good catalytic activity by reducing the methlylene blue (MB) also expressed antioxidant and antimicrobial activity than plant leaf extract. So, the present study was assessed the usage of the plant derived AgNPs in the field of drug design.
