Nanotechnology is an emerging area of science that involves the engineering of nano sized particles of various materials. Among the various nanoparticles, the silver nanoparticles are used in various applications due to their unique characters. The production of silver nanoparticles using a chemical method is harmful and produces toxic substances as by-products, so the aim of our study was to green synthesis silver nanoparticles using the fruit rind of Garcinia mangostana L. which is being discarded as a waste material. Aqueous rind extract of G. mangostana was prepared and synthesis of silver nanoparticles was analysed by UV-Vis spectrophotometer by optimizing various parameters like pH, time and concentration of extract. The nanoparticles were characterized using UV-Vis spectroscopy and the peak was obtained between the wave length of 410 - 433 nm in various treatments. The antibacterial activities of synthesized silver nanoparticles were tested against both gram negative (Pseudomonas) and gram positive (Staphylococcus) bacteria using the well diffusion method. The aqueous extract shows the remarkable zone of inhibition against Pseudomonas and Staphylococcus.
