Changes to metabolic activity following 48 h exposure to AC electric fields (+ Field) or current (+ Curr) at increased temperature (37°C), in the presence or absence of ZnO, on D425 cells in comparison to non-stimulated (NS) cells. Cells were treated with 5 µg/ mL ZnO NP for 4 h before electrical stimulation; NP were then removed and replaced with fresh cell culture medium. N = 3, n = 2. Results show mean ± SEM; **P = 0.0021, ***P = 0.0002, ****P < 0.0001
