Figure 5. Cell proliferation (MTT) assay.

Figure 5

Cell viability assay was carried out to assess the toxicity of the drug to nanoparticle in different ratios in both drug-sensitive and resistant cells. a, Drug-sensitive OVACAR8 and b drug-resistant OVACR8/ADR cells treated with nano-drug formulation for 48 hrs. The absorption was measured at 570 nm and the relative percentage of the control (untreated) cells, which were not exposed to the drug, were used to represent 100% cell viability. Nanodox showed higher toxicity to the cancer cells compared to free drug and drug free nanoparticle did not hinder the cell growth in both the cell types.
