Preparation of magnetic nanoparticles for magnetic fluid hyperthermia

In this paper, the determination and preparation of suitable magnetic material for magnetic fluid hyperthermia (MFH) is presented. It was suggested that the highest heating rate could be obtained by using maghemite with particle diameter of 15 nm. The heating rate of magnetite particle with diameter less than 10 nm was found to generate heat higher than that of cobalt and barium ferrites. Therefore, the magnetite with diameters ranging from 11-13 nm was selected for MFH. The magnetite nanoparticles with diameter of 12 nm was synthesized using standard coprecipitation method. The heat dissipation of magnetic particles with varying average diameters was also reported.
