Tumor Inhibition and US imaging. a US imaging of H2O2, FP NPs and FP + H2O2. b The ultrasound contrast images of tumor before and after injection of FP NPs. c Experimental flow chart of in vivo study. The variations of d body weight and e relative tumor volume of mice from different groups (n = 5, mean ± SD). f Tumor weights (n = 5, mean ± SD) and g images from each groups after sacrificing the mice on the 14th day. (h) H&E and Ki-67 staining of tumor tissues from the mice in different groups (scale bar: 100 μm). ***p < 0.001, **p < 0.01 and *p < 0.05
