In vivo antitumor assay demonstrated the most prominent tumor inhibition effect of anti‐CD47‐PCM@NP/PTX which suppressed the tumor volume from ≈200 mm3 to ≈160 mm3, proving consistent tendency with in vitro IC50 results (Figure6A, Figure S23 and Table S5, Supporting Information). The gene discussed is CD47; the disease is neoplasm.
