Survival of bacteria (~108 CFU/mL) incubated with PZnTEP for 30 min at 37 °C in the dark and irradiated with white light for different times. (A) S. aureus: (1) dark control, (2) 0.5 µM PZnTEP in dark, (3) 0.5 µM PZnTEP and 15 min irradiation, (4) 0.5 µM PZnTEP and 30 min irradiation, (5) 1.0 µM PZnTEP in dark, (6) 1.0 µM PZnTEP and 15 min irradiation, (7) 1.0 µM PZnTEP and 30 min irradiation; (B) E. coli: (1) dark control, (2) 1.0 µM PZnTEP in dark, (3) 1.0 µM PZnTEP and 15 min irradiation, (4) 1.0 µM PZnTEP and 30 min irradiation, (5) 1.0 µM PZnTEP + 100 mM KI in dark, (6) 1.0 µM PZnTEP + 100 mM KI and 15 min irradiation, (7) 1.0 µM PZnTEP + 100 mM KI and 30 min irradiation (* p < 0.05 compared with control).
