Scanning transmission electron (STEM) micrographs of HT1080 cells exposed to 80 µg/mL SiO2 (a), TiO2 (b), TiN (c), WO3 (d), HfO2 (e), and Au (f) nanoparticles for 24 h. Intracellular and cell-associated metal mass normalized to cell number as quantified by ICP-MS (g). Data in g expressed as mean ± SD from n = 4 biological repeats per data point examined over 2 independent ICP experiments.
