Amount of zinc in Caco-2 monocultured (a) and Caco-2/HT29-MTX cocultured cells (b) after 24 h treatment with digested ZnO NP (< 50 nm and < 100 nm) and ZnCl2. UC: untreated control; SC: solvent control (10% intestinal juice). Data are expressed as mean + SD; n = 5. Significant differences compared to SC (* P ≤ 0.05) were obtained by one-way analysis of variance/Ryan–Einot–Gabriel–Welsh post hoc test
