Figure Lengend Snippet: Synthesis and characterization of aCD47-CATE nanoplatform. (A) The preparation of aCD47-CATE nanoplatform. (B) UV-Vis absorption spectra of Croc under different pH. (C) The morphology of the aCD47-CATE nanostructure as visualized by transmission electron microscopy (TEM), scale bar = 100 nm (up) and scanning electron microscope (SEM), scale bar = 200 nm (down). (D) Changes in the zeta potential that occurred during the synthesis steps for both CATE and aCD47-CATE nanoplatform. Data are presented as mean ± SD (n = 3). (E) A characteristic high-angle annular dark-field scanning transmission electron microscopy (HAADF-STEM) micrograph, presented alongside the associated elemental distribution maps for the aCD47-CATE nanoplatform.
