Effects of Dox-loaded S3-DT on NPC cells. A The optimal loading efficiency of Dox was tested using fluorescence. B The efficiency of Dox release from S3-DT was tested using fluorescence. C The uptake of S3-DT-Dox by NPC cells was determined by flow cytometry. D–E The toxicity (D) and IC50 values of S3-DT-Dox in 5-8F and NP69 cells (E) were determined by MTS assay. The experiments were repeated thrice. *P < 0.05, ***P < 0.001
