In vitro cytotoxicity of chitosan-coated NPs and HA-functionalized NPs against Colon-26 cells, determined by MTT assays. Cytotoxicity of CPT-loaded NPs (a) and CUR-loaded NPs (b) at different concentrations against Colon-26 cells after co-incubation for 24 or 48 hours. Triton X-100 (0.5%) was used as a positive control to produce a maximum cell death rate (100%), whereas cell culture medium was used as a negative control (death rate de?ned as 0%). Cytotoxicity is given as the percentage of viable cells remaining after treatment. Each point represents the mean ± S.E.M. (n = 5).
