In vivo biodistribution and tumor targeting effect of nanosheet. A FMI images of tumor-bearing mice after intravenous administration of IR780 and FA-BSA-PEG/MoOx@IR780 at different time points; B ex vivo FMI images of the main organs retrieved from tumor-bearing mice at 24 h time point after intravenous administration of IR780 and FA-BSA-PEG/MoOx@IR780. The H, Li, S, Lu, K, and T represent the heart, liver, spleen, lung, kidney, and tumor, respectively; C quantitative analysis results of ex vivo mean fluorescence intensity of tumors and main organs. The near-infrared thermal images of the mice (D) and the temperature changes of the tumors (E) by intravenous administration of normal saline, FA-BSA-PEG/MoOx and FA-BSA-PEG/MoOx@DTX, respectively
