In this work, sensing and photocatalytic activities of green synthesized silver nanoparticles (Ag NPs) are investigated. Ag NPs have been by the reduction nitrate (AgNO3) using different leaf extracts. An optimum surface plasmon resonance (SPR) behavior is obtained for neem extracts because presence a high concentration diterpenoids, as evidenced from gas chromatography mass spectroscopy results. The underlying mechanism formation highlighted. in spherical shape exhibit hexagonal crystal phase also show good stability. biosensing property evaluated mancozeb (MCZ) agro-fungicide, SPR peak position exhibited linear response with MCZ concentration. sensitivity found to be 39.1 nm/mM. Further, activity tested 0.5 mM solution model under UV–visible illumination. It observed that caused reactive oxygen species. Therefore, potential candidates applications.
