Figure 2

Target distribution of magnetic CTS-Fe₃O₄ in liver and lung tissue. Figures were shown by Prussian blue and neutral red staining (×250), with outer static magnetic field for 2 hours. (a) Normal liver tissue; (b) liver tissue injected CTS-Fe₃O₄ nanoparticles (1 mM); (c) normal lung tissue; (d) lung tissue injected CTS-Fe₃O₄ nanoparticles (1 mM). Scale bars correspond to 10 μm.
