Scanning electron microscopy observations after NPs exposure. IP15 and HK-2 morphology was observed using Scanning Electron Microscopy (SEM). IP15 cells (a) were exposed for 24 h with different NPs: ZnO (2.5 μg/cm2) (c), CdS (5 μg/cm2) (e) and TiO2 (5 μg/cm2) (g). HK-2 cells (b) were exposed for 24 h with different NPs: ZnO (2.5 μg/cm2) (d), CdS (5 μg/cm2) (f) and TiO2 (5 μg/cm2) (h). (SEM scale bars (a, g, f): 10 μm, (b, d, e, h): 20 μm and (c): 100 μm). Images were taken at x 2500, 1000 and 200, respectively).
