Micronuclei of Caco-2 (a) and LT97 cells (b) after treatment with ZnO NP < 50 nm and <100 nm for 24 and 48 h, respectively. SC: solvent control (Millipore water); MMC: 2.5 µg/mL mitomycin C; VB: 25 ng/mL vinblastine; 307 µmol/L ZnCl₂ for Caco-2 cells and 12 µmol/L ZnCl₂ for LT97 cells. The data are normalised to the untreated control (=1; dashed line) and are expressed as the mean + standard deviation; n = 3. Significant differences compared to the untreated control (* p  ≤  0.05) were obtained by one-way analysis of variance/the Ryan-Einot-Gabriel-Welsh post hoc test.
