Green synthesis and Characterization of silver nanoparticles from Solanum tuberosum peel waste: Efficacy assessment through antimicrobial and antilarval activities

Silver nanoparticles serve as potent antimicrobial agents. In this study, we report the green synthesis of silver nanoparticles using Solanum tuberosum peel extract, followed by characterization via UV-Vis spectroscopy, SEM, and FTIR analysis. Antimicrobial efficacy against Escherichia coli, Staphylococcus aureus, and Candida albicans was evaluated using agar well diffusion, and activity of StAgNPs was compared with antibiotics like CAZ, TZP and NOR, with MIC and MBC values measured. Antilarval activity against Aedes aegypti larvae was also assessed. Results indicated successful nanoparticle formation (peak at 450 nm, 80–100 nm spherical particles) and notable antimicrobial and antilarval effects at higher concentrations. These findings highlight the non-toxic, eco-friendly potential of the green synthesized nanoparticles, with applications in antimicrobial therapies and vector control, although further validation is required.
