Fig. 6. (a) In vivo fluorescence imaging of mice bearing SCC-15 tumors at different time points after the in situ injection of NS, free DOX, and NDHM (the dose of DOX at 5 mg kg−1); (b) average fluorescence intensity of the tumor site by quantitative analysis. Data represent means ± SD (n = 3); (c) ex vivo fluorescence imaging of the tumor and main organs at 5 d; and (d) average fluorescence intensity of the tumor and main organs by quantitative analysis. Data represent means ± SD (n = 3).
