Percentage of DNA in the tail of the comet in amniotic cells (ordinate) after 48 h exposure time (A) and after 72 h exposure time (B) to TiO₂-NPs, lincomycin and their combination (abscissa). The dark bar is negative control; the white bar is 10 μg/L TiO₂-NPs treated cells; the dark grey bar is 100 mg/L lincomycin treated cells; the light grey bar is 10 μg/L TiO₂-NPs + 100 mg/L lincomycin treated cells; the striped bar is 10 mM H₂O₂ treated cells. * p ≤ 0.05.
