Preparation of magnetite/iodinated oil dispersion and its heating property

摘要：

After treated with oleic acid (OA), the magnetite particles prepared by co-precipitation were dispersed in iodinated oil and then magnetite/iodized oil dispersion were obtained. The magnetic properties, stability and heating property of the dispersion were studied. Moreover, the vivo experiment was employed to research the heating ability and hyperthermia security of the dispersion. The experi-. ment results demonstrated that the magnetite/iodized oil dispersion was of superparamagnetism and stability and could produce strong heat effect in the alternating magnetic field. The Specific Absorption Rate (SAR) value was calculated to be 121 W/g. Furthermore, the results of heating experiment in vivo demonstrated that the heat generated by the magnetite/iodized oil dispersion could heat tumor to the hyperthermia temperature. The heat tumortargeting property and heat security of the magnetite/iodized oil dispersion was confirmed.
