Localization of crystalline anatase and rutile TiO₂ NPs in HepG2 cells. Confocal microscopy of reflection images was used also to verify the location of TiO₂ NPs in HepG2 cells. (a) Control HepG2 cells without TiO₂ NP exposure; (b) cells exposed to 10 μg/mL crystalline anatase TiO₂ NPs for 48 h; (c) cells exposed to 10 μg/mL crystalline rutile TiO₂ NPs for 48 h.
