Microwave-mediated green synthesis of silver nanoparticles using glycosmis pentaphylla leaf extract and exploration of their antimicrobial properties

Abstract

 Over the past few decades, nanotechnology emerged as one of the most significant area of research in material science. Due to the remarkable physical, chemical, optical, and biological features, noble metal nanoparticles like gold, silver, palladium, and platinum are broadly used in various fields. In this study, a quick microwave-assisted, inexpensive, and environmentally friendly method was used to synthesize silver nanoparticles (AgNPs). Without using any harmful chemical substances, AgNPs were generated using Glycosmis pentaphylla leaf extract as a reducing and stabilizing agent. UV-visible spectrophotometry, X-ray diffraction, and Scanning electron microscopy were used for the evaluation of successful synthesis. The presence of AgNPs confirmed by the appearance of peak at 417 nm utilizing UV-Vis method and also established by X-ray diffraction patterns. The synthesised AgNPs were also examined for antimicrobial activity using the agar well diffusion method and found that synthesized AgNPs efficiently inhibited the growth of various gram-positive and gram-negative bacteria.
