Synergistic cancer treatment properties of BiVO₄/Fe₃O₄@PDA SPs in vivo. Mice are randomly divided into 7 groups with 5 mice in each group. a Relative tumor volume curves of mice during 16 d. b Average tumor weights at the end of treatment. c Tumor photographs at the end of treatment. d Body weight curves of mice during 16 d. e Photographs of mice at the end of treatment. f H&E staining of tumor at the end of treatment (scale bar is 50 µm). P-values were calculated by one-way ANOVA: *P < 0.05, **P < 0.01
