Figure 3. Killing of bacteria added to photoactivated TiO2 after light.
TiO2 (10 mM) was stirred with NaBr (0, 10, or 100 mM) under UVA light (40 J/cm2). MRSA (A) or E. coli (B) cells (10(8) cells/mL) were then added at 0, 30 or 120 minutes after the end of the illumination and incubated for 1 hour. Values are means of 3 repetitions and bars are SD.
