Viability of cells after treatment with various concentrations of DOX (0.001; 0.005; 0.05; 0.15; 0.5; and 3 µg/mL) for DOX, Lipo-DOX, DOX-FA 10 µg/mL, DOX-FA, and Lipo DOX-FA, towards (a) LLC cell, (b) HeLa cell and (c) HEK cell; and various concentrations of FA (0.5; 1; 5; 10; 50; and 180 µg/mL) for FA, Lipo-FA, FA + DOX-FA 0.15 µg/mL, DOX-FA, and Lipo-DOX-FA toward (d) LLC cell, (e) HeLa cell and (f) HEK cell. Cells were then incubated for 48 h before the MTT reagent was added. The IC50 and CC50 values in a-c refer to the DOX concentration, while the d-f values relate to FA concentration.
