Confocal microscope z-scans of Caco-2/HT29 co-culture barriers after TiO2NPs-S (a and b), TiO2NPs-R (c and d), and TiO2NPs-W (e and f) exposures lasting for 24 h (a, c and e), or 48 h (b, d and f). Cell nuclei (blue) were stained with Hoechst and cell membrane and mucus (red) with WGA. NPs were visualized by reflection and marked with a green mask. Images were processed with the Imaris 7.2.1 software
