GREEN SYNTHESIS OF SILVER NANOPARTICLES FROM MUNTINGIA CALABURA FRUIT EXTRACT AND ITS BIOLOGICAL ACTIVITY
AbstractSynthesis of silver nanoparticles using fruit extract has been gaining considerable attention as an eco-friendly approach in green chemistry. The present work reports the synthesis of Muntingia calabura silver nanoparticles (McAgNPs) by the addition of an appropriate amount of Muntingia calabura fruit extract to the aqueous AgNO3 solution under constant stirring at room temperature for 24 h. The addition of fruit extract leads to the formation of stable colloidal silver nanoparticles. The peak obtained at 460 nm using UV-VIS spectroscopy confirmed the formation of silver nanoparticles. Scanning electron microscopy analysis showed the spherical and oval morphology of the silver nanoparticles. Energy-dispersive X-ray spectroscopy (EDS) analysis indicated the abundance of silver nanoparticles in chemical composition. DLS/ZETA POTENTIAL analysis was applied in order to measure the particle size distribution and nature of the surface charge of the McAgNPs. Further, the antibacterial activity against the silver nanoparticles was established.
