Debridement of Bacterial Biofilms with TiO₂/H₂O₂ Solutions and Visible Light Irradiation

Figure 1

Regrowth of S. epidermidis after different debridement treatments. Background fluorescence from TSB was subtracted from all test groups. (a) Average fluorescence intensity measured during reincubation after debridement with different treatments (n=8). (b) Average fluorescence intensity after 3 h regrowth. Groups with an asterisk indicate statistically significant difference compared to the control PBS (Dunnett post hoc test, p≤ 0.05). Groups with different letters are significantly different (five test groups compared, Tukey post hoc test, p ≤ 0.05).
