In the pharmacokinetics study, the tumor accumulation of the DiD‐labeled nanoparticle core in the PCM@NP/DiD and anti‐CD47‐PCM@NP/DiD groups was also efficiently prolonged compared to the NP/DiD group (Figure S13, Supporting Information), which was of considerable significance for its further application and druggability. Here, CD47 is linked to neoplasm.
