Figure 2. Effect of bromide concentration on antimicrobial TiO2 photocatalysis.
Cells were stirred in the presence of 10 mM TiO2 with addition of a range of concentrations of NaBr while being exposed to increasing fluences of UVA light. (A) MRSA (0–1.5 mM NaBr); (B) E. coli (0–10 mM NaBr); (C) C. albicans (0–10 mM NaBr). Values are means of 3 repetitions and bars are SD.
