ROS production after NPS exposure. Effects of TiO2, ZnO and CdS NPs on ROS generation by IP15 (a) and HK-2 (b) cells. Cells were exposed in RPMI medium with different concentrations of NPs for 4 h, TBHP at a concentration of 50 μM were applied as positive control. The data are presented as the mean ± SE of at least three independent experiments. Data were expressed as the percentage of the ROS level in control group. Significance indicated by: *p < 0.05 versus control cells.
