Cytotoxicity and genotoxicity tests. A Quantitation of the necrotic tissue revealed by Trypan blue staining in Vicia faba tissues after exposure to low (50 mg kg−1) and high (100 mg kg−1) doses of nanomaterials. B Representative images of faba bean leaves stained by Trypan blue and collected from seedlings exposed to high doses of nanoparticles. C MN frequencies measured in samples treated with 100 mg kg−1 of NPs for 24 h and 72 h or exposed to negative (CNT) or positive (PC, 10–4 M maleic hydrazide, 4 h) control conditions. D Mitotic indices of samples (100 mg kg−1 of NPs) and relative controls (negative, CNT; positive, PC) treated for 24 h and 72 h. The asterisks denote significant differences of the samples from the control (one-way ANOVA/LSD test; **p < 0.01)
