The in vivo toxicity of CS-C₆₀-Fe₃O₄ in nude mice model. The MHCC97-H cells were cultured and injected into the nude mice to form the subcutaneous tumor model. The CS-C₆₀-Fe₃O₄ was injected into nude mice via tail-vein. The results were shown as images of tumor tissues: A tumor volumes, B tumor weights, C *P < 0.05
