Preparation and characterization of CS-C₆₀-Fe₃O₄. A Basic synthetic route of CS-C₆₀-Fe₃O₄ in the present study. Schematic diagrams of the synthesis of CS-C₆₀-Fe₃O₄ (the pink ball represents Fe₃O₄, the chemical structure of the polymer chitosan and the structure of fullerene C₆₀ are also illustrated). B Hydrodynamic size distribution of CS-C₆₀-Fe₃O₄ by dynamic light scattering (DLS). C Transmission electron microscopy (TEM) images of CS-C₆₀-Fe₃O4. D Fourier transform infrared (FT-IR) spectrum of CS-C₆₀-Fe₃O₄. (E) Electron paramagnetic resonance (EPR) spectra of •OH captured by DMPO. F Separation of CS-C₆₀-Fe₃O₄ nanoparticles by magnetic effect. G Inhibition rates of CS-C₆₀-Fe₃O₄ and other agents on cell lines. The results were shown as heat-map image (G)
