Tissue distribution of EL35-C₆₀ and CS-C₆₀-Fe₃O₄ in nude mice under different conditions. After obtaining MHCC97-H cells in culture, the cells were inoculated into nude mice to form subcutaneous tumor tissues. Thereafter, half of the animals had supermagnets attached to the tumor tissue, while the other half did not have magnets attached. The animals were collected at different time points and the C₆₀ content of each type of tissue and organ was assayed to determine the final distribution of C₆₀ in the organs and tissues of nude mice under different conditions based on organ weight and C₆₀ content. The legend shows the main organs or tissues, where others represent the amount of C₆₀ in the spleen, brain, bone, and other tissues and organs as well as the amount of C₆₀ metabolised
