Fig. 4. Cell viability of HeLa, MCF 7 and CHO cells after 24 h of exposure to RuBDP NPs over a range of concentrations. Live cells were treated with the nanoparticles followed by the addition of resazurin for 6 h. Absorbance readings at 570 nm with a background at 600 nm were performed. Data were expressed as averaged percentages and compared to non-treated cells. P ≤ 0.05; ***P ≤ 0.01, ****P ≤ 0.0001.
