The biosynthesized AgNPs were characterized using UV–Vis spectroscopy, XRD, FTIR, SEM, and EDS techniques, confirming their successful formation and structural properties. The antibacterial efficacy of the AgNPs was assessed against Escherichia coli and Listeria monocytogenes, achieving 99.5% inactivation for E. coli and 99.3% inactivation for L. monocytogenes after 120 min of visible light exposure. Additionally, the AgNPs showed notable anticancer effects against breast cancer cells (MDA-MB-231), displaying a dose-dependent decrease in cell viability, with reductions of 15%, 30%, 72%, and 86% observed at concentrations of 25, 50, 75, and 100 μg/mL, respectively.

A variety of techniques, comprising UV–Vis, XRD, FT-IR, FE-SEM with EDAX, and TEM, have been employed to investigate the formed TiO2 NMSP. The germicidal properties of formed TiO2 NMSP towards germs have been investigated by implementing an agar-based pore plate technique. Congo red and methylene blue dyes have been applied to assess photodecomposition activity. The TiO2 NMSP exhibited significant germicidal efficacy versus many pathogenic microbes. The maximum degradation percentages of Congo red and methylene blue were 89.2% and 83.7%, achieved after 60 and 70 min, respectively. Consequently, it is determined that the selected NMSP composition enhanced germicidal and photodecomposition capabilities.
