Ex vivo analysis of major tissues. (A) Immunofluorescence-staining analysis shows that the tumor tissue slices in the test group had obvious fluorescent signals and that there was no fluorescent signal in the control group. (B) Prussian blue-staining results show that the tumor tissue slices in the test group had blue iron particles, and that there was no iron particle in the control group. (C) The ICP-MS results show that FMNPs were mainly distributed in the tumor tissues of the test group.
