ROS production after NPS exposure. Effects of 5 μg/cm2 of CB (FW2, P60 and LB101) and TiO2 (15 and 50 nm) NPs on the oxidation of DFCH-DA to DCF in IP15 cells and LLC-PK1 cells, after 6 h. Data represent the mean ± SE of fluorescence ratios (fluorescence of exposed cells/fluorescence of unexposed cells controls). *p < 0.01 indicates significant differences compared to control.
