Aggregation of CS-C₆₀-Fe₃O₄ in subcutaneous tumor tissue induced by magnetic fields. MHCC97-H cells were obtained in culture, after which MHCC97-H cells were inoculated with nude mice to obtain subcutaneous tumor tissue. CS-C₆₀-Fe₃O₄ was administered to the experimental animals by tail vein injection. Adhesion to the surface of subcutaneous tumor tissue in nude mice was used to induce enrichment of CS-C₆₀-Fe₃O₄ in subcutaneous tumor tissue
