Bacterial reduction in percentage of (a) S. aureus and (b) K. pneumoniae on cotton fabrics with and without Mn-doped TiO₂ NPs in the dark and under natural sunlight. NPs0, NPs10, NPs25 and NPs50 are cotton fabrics with zero, 10, 25 and 50 wt% Mn-doped TiO₂ NPs; NPs50W is the NPS50 after 10 washing cycles. (c) Schematic of visible light induced the photocatalytic inactivation of bacteria and degradation of stain residues on contaminated fabric with Mn-doped TiO₂ NPs.
