Microbial antibiotic resistance is increasing due to release of hazardous chemicals into the environment. Anthropogenic activities have made the microbial world more resistance towards the conventional antibiotics. The biosynthesized nanoparticles are challenging particles and bactericidal in nature in treating waste water. Nano size of the particles has high caliber in removing the pollutants from the water by the adsorption phenomenon. . The present study emphasizes on the green synthesis of nanoparticles from the tamarind shell extract, an agricultural waste, commonly used as a fuel by direct burning. Tamarind shell, being rich in calcium and other organic compound, is used as reducing and capping agent in converting the silver to silver nanoparticles which is then characterized using XRD showing cubic crystalline structure, FTIR depicting the functional group, UV-Vis with a peak at 430nm spectrophotometer and TEM showing an average particle size of 25nm.the characterized silver nanoparticles were subjected to the antibacterial activity. the antibacterial sensitivity were recorded on gram negative and gram positive bacteria like E-coli, Streptococcus spp, Staphylococcus aureus, Klebseilla spp and Pseudomonas aeruginosa . Thus the result obtained proves the ability of silver nanoparticles as the future prospects of research in medicine and pollution remediation
