Viable counts of EMRSA-16 after incubation at 20 °C on modified polyurethane squares for (a) 2 h in the dark and (b) 2 h with exposure to standard laboratory white light (500 ± 300 lx). *Bacterial counts were reduced to below the detection limit of 100 cfu/mL. DOPA indicates NPs synthesized with DOPA capping. Error bars are based on the standard deviations of three experimental replicates.
