(A) Treatment schedule of in vivo antitumor therapy. (B) NIR fluorescence image and (C) photothermal images of 4T1 tumor-bearing mice injected with IT-4 F NPs. (D) NIR fluorescence images of major organs at different time intervals after IT-4 F NPs injection. Time-dependent changes of tumor volume (E and F), tumor images and tumor weight (G) and body weight (H) of mice in different groups. (I) Survival rate after various treatments. (J) Representative images showing that mice in the IT-4 F NPs + L treatment group had fewer lung metastases, and H&E staining images of lung tissue (where circles indicate metastatic tumors). (K) Microscopic images of organoids following different treatment conditions
