Fig. 1From: In vitro detection of in vitro secondary mechanisms of genotoxicity induced by engineered nanomaterialsContrast inverted HAADF STEM electron micrographs showing dSPION uptake in mono-cultured 16HBE14o− cells and DTHP-1 macrophages. Uptake of γ-Fe2O3 is shown in 16HBE14o− cells (a) and dTHP-1 macrophages (c). Uptake of Fe3O4 is also shown in DTHP-1 macrophages (e). Regions highlighted in red boxes are displayed at higher magnification in adjacent images (b, d and f respectively)Back to article page
