Figure 6. Activation of ROS-specific fluorescence probes by photoactivated TiO2.
Probe was illuminated with UVA light (TiO2 (10 mM) was illuminated with UVA light (0–3 J/cm2) in the presence of NaBr (10 mM), TiO2 (10 mM) or both (10 mM NaBr + 10 mM TiO2). Fluorescence was measured in plate reader after each aliquot of light. (A) SOSG; (B) HPF. Values are means of 6 wells and bars are SD.
