In vivo dual-modal imaging. a Cross-sectional PA images of the HT-29 tumor xenograft in a mouse model after intravenous injection of ICG-Fe NPs ([ICG] = 3.75 mg/kg). b In vivo and c ex vivo fluorescence images of a HT-29 tumor-bearing mouse after intravenous injection of free ICG and ICG-Fe NPs. Excitation (740/30 nm) and emission (790/20 nm) filters were used for fluorescence imaging. The red dotted circles in b indicate the tumor region. Tumors and other organs were collected 24 h post injection: L: liver, Sp: spleen, K: kidney, Lu: lung, H: heart, T: tumor
