The in vivo evaluation of anti-tumor activity of Fe-CDs. a Distribution of Fe-CDs in tumor-bearing mice using an in vivo imaging system. b Photographs of tumor-bearing mice at different treatment times of PBS and Fe-CDs. c Photographs of tumors collected from different groups of mice after 21 d treatment of PBS (left) and Fe-CDs (right). d Mean tumor volume versus time curve of PBS and Fe-CDs treatment groups. e Mean weight of tumors of PBS and Fe-CDs treatment groups at 21 d. f Mean body weight of normal mice after intravenous administration of PBS and Fe-CDs for different days. g Histological analysis of cancerous tissues by H&E staining after treatments with PBS and Fe-CDs. (significance analysis was performed using one-way ANOVA method. ns: not significant, ***p < 0.001, n = 6)
