(A) Effects of CCA5-NPs on the proliferation ability of L929 cells (24 h), ** p < 0.01:2 mg/mL vs other concentrations; (B) Light microscopy (LM) and fluorescence microscope (FM) images of L929 cells treated with CCA5-NPsand FITC-CCA5-NPs: 1 h, 2 h,4 h and 12 h, the scale bar represents 25 µm; (C) FM images of L929 cells treated with FITC labeled CCA(1–5)-NPs, the scale bar represents 25 µm; (D) Cellar uptake efficiency of CCA(1–5) nanoparticles by L929 cells at various time(1,2,4 and 12 h), ** p < 0.01: 12 h vs 1 h and 4 h (CCA5-NPs).
