Cytotoxicity of CM-Cu2O NPs in HDF, MDA-MB-231, SKBR3 and T-47D cells. a CM-Cu2O NPs decreased growth and proliferation of HDF, MDA, SKBR and T47D cells in concentration-dependent manner in all the time of incubation by MTT method and b Flow cytometry assays assess the apoptotic activity of paclitaxel-treated cells in HDF, MDA-MB-231, SKBR3 and T-47D at 24, 48 and 72 h post-treatment
