Inactivation of microorganisms by NSMs: E. coli with Ag@TiO₂ (a) under visible light and (b) in dark; S. cerevisiae with Ag@TiO₂ (c) under visible light and (d) in dark; (e) E. coli with TiO₂-Cu²⁺; (f) S. cerevisiae with TiO₂-Cu²⁺. As positive control, Ag⁰ for Ag@TiO₂ and CuSO₄ for TiO₂-Cu²⁺. Bars represent standard deviation; each treatment was performed in triplicate.
