A green synthesis technique, which is economical and environmentally sustainable, was used to synthesize AgNPs, and several methods were employed to characterize the nanoparticles, such as UV-Vis spectroscopy, SEM, TEM, and FTIR. The produced AgNPs demonstrated noteworthy antibacterial and antifungal attributes. Unique absorption peaks were observed in the UV-Vis spectra, indicating successful AgNP synthesis. According to SEM and TEM examinations, the nanoparticles had a steady average size of 48 nm and were spherical. When the antibacterial activity was tested against several bacterial strains, it showed significant inhibitory effects. This research underscores the potential of AgNPs in various applications, including medical devices, environmental remediation, and consumer products, to combat antibiotic resistance and infection control for good health and well-being, as outlined in Sustainable Development Goal 3 (SDG3). AgNPs can act as efficient catalysts for various chemical reactions, including organic synthesis, environmental remediation, and energy storage, SDG 12 (Responsible Consumption and Production). Green-synthesized AgNPs can be used to remove pollutants from water and soil (SDG 6: Clean Water and Sanitation). This study investigates the synthesis, characterization, and utilization of silver nanoparticles (AgNPs), emphasizing environmentally sustainable production methods and providing valuable perspectives for future developments in nanomedicine and associated fields.
