In vitro cellular uptake of nanomicelles. a, b The evaluation of in vitro cellular uptake of CFPE-labeled nanomicelles by flow cytometry. c, d In vitro cellular uptake of nanomicelles evaluated by HPLC. The intracellular uptake of gefitinib = intracellular uptake of gefitinib concentration/intracellular protein concentration × 100%. One-way ANOVA with the Newman–Keuls post-test was taken to compare the two groups. Data are expressed as mean ± SD (n = 3)
