Biodistribution and therapeutic effect of MCMD NPs. A The images of free Cy7 and Cy7-MCMD NPs accumulated at the tumor site at selected time-points. B The fluorescence images of tumors and organs from mice at 48 h after injection. C Average fluorescence intensity of organs and tumors in each group. D Tumor images. E Average tumor weight of each group. F The curves of tumor growth of tumor-bearing mice. G The survival curves of tumor-bearing mice. Data were expressed in the form of mean ± SD (n = 5). *P < 0.05, **P < 0.01, ****P < 0.0001
