Fig. 8. Biocompatibility studies of Mn3O4@PEG-GMBP1 NPs and Mn3O4@PEG NPs in healthy mice. (a) The survival rate of healthy mice injected with different concentrations of Mn3O4@PEG-GMBP1 NPs or Mn3O4@PEG NPs; (b) H&E staining of the hearts, livers and kidneys of mice harvested 14 days after injection with Mn3O4@PEG-GMBP1 NPs or Mn3O4@PEG (dose: 150 mg kg−1). Healthy mice treated with PBS were used as the control. Scale bar: 100 μm.
