Figure 1. (IMAGE) Science China Press Caption The development of TR4@Lipo with self-indicating property and its behaviors on cellular uptake when exposed to media containing different concentration of serum. (A) Molecular structure of TR4. (B) Schematic illustration of TR4@Lipo. TR4 generates blue fluorescence when incorporated into the liposomes. (C) Confocal images of MCF-7 cells after incubation with TR4@Lipo in the presence of different concentrations of FBS from 0% to 10%. The scale bar is 10 μm. Co-localization profiles are shown in the bottom panel.
