Effect of CdS-MD nanoparticles on cell viability of human cell lines. (A) Effect of CdS-MD nanoparticles on cell viability on HepG2, MDA-MB-231, and CaCo-2 cells. Cells were exposed in cultured medium with different concentrations of CdS-MD nanoparticles for 24 h. Results are expressed as percentage of cell viability as compared to control group. Data are presented as the mean ± SD of at least three independent experiments. *p <0.05 as compared with control group. (B) Morphological analysis of each cell line treated with 8.20 nM of CdS-MD nanoparticles; black arrows indicate apoptotic cells and white arrows indicate cells in division (40X).
