摘要：In this report, a simple photo-catalytic rapid green synthesis methodology has been developed forbiosynthesis of silver nanoparticles (AgNPs) using aqueous extract Tamarindus indica (AET) leaves. The developedprocess was able to synthesize AgNPs within 5 min without any instrumental support. External reducing agent or stabilizeris not required because AET alone acts as phyto-reducer and capping agent. Rapid change in color of reaction mixture fromyellowish green to reddish brown within 5 min in direct sun light was primary indication of AgNPs synthesis. UV–visiblespectroscopy confirmed the biosynthesis through SPR band for AgNPs at λmax of 432 nm. The process parameters weremanually optimized and then produced AgNPs were systematically characterized using FESEM, EDX, HRTEM, XRD andFTIR techniques. AgNPs were discrete and spherical with average size distribution of 32.4 nm. Particle crystalline in natureand their crystal lattice was of face centered cubic (fcc). Synthesized AgNPs showed good antibacterial potential againstboth Gram positive and Gram negative bacteria.
