HeLa cell viability after incubation with free MTX, MTX-loaded FTC-NPs, and MTX-loaded CHT-NPs at 0.1, 1, and 10 μM for 24, 48, and 72 h evaluated using the MTT assay. The results are expressed as the percentage of the control assumed as 100%. Each value represents the mean ± SD of three independent experiments. • p < 0.05 vs. control; * p < 0.05 vs. CHT-coated liposome-treated cells.
