a) Schematic diagram of KI@DOX‐Mn₃O₄‐Kaol_C12N. b) Digital photos (b1) and tumor‐volume change and microscopic images (b2) of tumor sections of tumor‐bearing nude mice after the implantation and antimetastasis assay results (b3,b4) of control, Mn₃O₄‐Kaol_C12N, DOX‐Mn₃O₄‐Kaol_C12N, and KI@DOX‐Mn₃O₄‐Kaol_C12N. c) In vivo imaging before and after (0 and 5 min, respectively) intra‐tumor administration of KI@DOX‐Mn₃O₄‐Kaol_C12N (top‐right corner shows magnified images of corresponding circled area). d) Microscopic sectional images and biodistribution of KI@DOX‐Mn₃O₄‐Kaol_C12N in tumor and main tissues.
