Evaluation on targeting function of photonanomedicine. A Fluorescence images of tumor-bearing mice after intravenous injection of Apt-lacking photonanomedicine and photonanomedicine. The red circle marked the tumor site. B The semi-quantitative analysis of fluorescence intensity in tumor sites based on part A. Fluorescence photographs C and mean fluorescence intensity D of tumor tissues and other major organs at 72 h after intravenous injection. E Schematic illustration of photonanomedicine targeting the Raji cell surface. F The distribution of Apt-lacking photonanomedicine and photonanomedicine in tumor tissues at 72 h post-i.v. injection. Data were presented as means ± SD, ***p < 0.001, compared with the corresponding control group
