The synthesis of metal nanoparticles (NPs) through plant-mediated methods has garnered significant attention due to its eco-friendly and cost-effective nature. In this study, we investigated the fluorescent properties and catalytic activities of metal nanoparticles synthesized using various plant extracts. “The synthesis process involved the reduction of metal ions by phytochemicals present in the plant extracts, leading to the formation of stable metal nanoparticles. The fluorescent properties of the synthesized nanoparticles were characterized using spectroscopic techniques, revealing unique emission spectra indicative of their potential applications in bioimaging and sensing. Additionally, the catalytic activities of these nanoparticles were evaluated in various chemical reactions, showcasing their efficiency as heterogeneous catalysts. Our findings underscore the promising role of plant-mediated synthesis in tailoring the properties of metal nanoparticles for diverse applications in fields ranging from biotechnology to environmental remediation.
