Fig. 2From: Synthesis, characterization and biocompatibility of cadmium sulfide nanoparticles capped with dextrin for in vivo and in vitro imaging applicationEffect of CdS-Dx/QDs on cell viability of human cell lines. a Effect of CdS-Dx/QDs on cell viability in HepG2, HEK293, and HeLa cells. Cells were exposed in cultured medium with different concentrations of nanoparticles for 24 h. Results are expressed as the 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 groupBack to article page
