(a) In vivo real-time and in vivo fluorescence imaging of SMMC7721/S tumor-bearing mice with intravenous injection of MCS NPs. (b) Fluorescence intensity changes in tumor tissues at different time points (n = 3, mean ± SD). (c) Ex vivo fluorescence images of the tumor and main organ tissues dissected from mice at 12 h. (d) Thermal imaging of tumor-bearing mice injected with saline or MCS NPs under 660 nm laser irradiation for different times. Saline: inject with physiological saline, MCS NPs: inject with MCS NPs. (e) Heating curves. (f) In vivo T2-weighted MRI of SMMC7721/S tumor-bearing mouse models.
