Abstract
The synthesis of nanoparticles using green chemistry method is an intensifying research area due to the prospective applications in nanomedicines. The purpose of this present study was to develop a simple phyto-assisted method for the synthesis of silver nanoparticles (AgNPs) using Garcinia mangostana stem aqueous extract as reducing agent. The formation of AgNPs was confirmed by surface plasmon resonance as determined by UV–visible spectra at 430 nm. The morphology (SEM), diffraction pattern (XRD), elemental analysis (EDX) and visible absorption spectroscopy (UV–vis) confirmed the reduction of silver ions to AgNPs with the above characterization. The XRD data predicted the characteristic diffraction peaks of the elemental silver phases and the SEM image showed spherical nanoparticles in monodisperesed nature. The antibacterial assessment of AgNPs was analyzed by measuring the inhibitory zone.
