(A) Cellular uptake of FA-Se@DOX (red fluorescence) was visualized by red fluorescence from DOX in A549 cells (A) and HeLa cells (B). Nucleus was indicated by blue fluorescence. Scale bar is 40 μm. (C) The cellular uptake efficiency of DOX, Se@DOX, and FA-Se@DOX was analyzed by flow cytometry. (D) Effects of endocytosis inhibitors and temperature on the internalization of FA-Se@DOX. * p < 0.05, ** p < 0.01 vs. control group.
