Transmission electron microscopy observations of NPs uptake. IP15 and HK-2 uptake and subcellular localization of NPs were observed using Transmission Electron Microscope (TEM). IP15 (a) and HK-2 (b) cells were exposed for 24 h with TiO2 (5 μg/cm2) and EDS spectra were performed in cells (c). IP15 (d) and HK-2 (e) cells were exposed for 24 h with CdS (5 μg/cm2) and EDS spectra were performed in cells (f) (Labels: n, nucleus; v, vesicle; arrows, NPs aggregates (TEM scale bars (a): 2 μm, (b): 4 μm, (c): 1 μm and (d): 2 μm). Images were taken at × 5K, 3.5K, 13K and 3.5K, respectively).
