Figure 7

A) In vivo time‐dependent fluorescence image of tumors in CT26 tumor‐bearing mice. B) In vitro imaging of the livers, hearts, spleens, lungs, kidneys, and tumors excised from CT26 tumor‐bearing mice after 48 h (1. Control group, 2. CPT‐TK‐HPPH/Pt NP, 3. CPT‐TK‐HPPH NP, 4. HPPH). Quantitative fluorescence intensity of C) in vivo and ex vivo tumor tissues measured by RIO value. D) Fluorescence images of ex vivo tissues (blue channel: DAPI, red channel: HPPH, scale bar: 100 µm). All quantitative data are presented as mean ± SD (n = 3). “**” means the P < 0.01.
