SEM analysis of human cell lines. (a–c) MCF7 (top, the red arrows indicating the nanoflakes onto the cell), (d–f) U937 (middle, the blue arrows indicating the damaged areas and the red the nanoflakes) and (g–i) HaCaT cells (bottom, the blue arrows indicating the damaged areas and the red the nanoflakes) untreated and treated with MoS2 dispersion at the indicated concentrations. The \(\bar{N}\) was two at 10 μg/mL and six at 14 μg/mL.
