In vitro cellular uptake of RL-NP-DOX-ERL in SCC7 tumor cells. a Confocal microscopy images reveal cellular uptake of free DOX, NP-DOX-ERL, and RL-NP-DOX-ERL. Red and blue colors indicate DOX and Hoechst, respectively. b Flow cytometric analysis of SCC7 cells after treatment with free DOX, NP-DOX-ERL, and RL-NP-DOX-ERL. c Pearson correlation coefficients between the fluorescence signals from DOX and Hoechst in confocal images (***p < 0.001). d Fluorescent images of SCC7 cells after treatment with free DOX, NP-DOX-ERL, and RL-NP-DOX-ERL (different concentrations)
