| Research Abstract |
For the application of magnetic hyperthermia, the heat source of magnetite nanoparticles (MNPs) were synthesized by a thermal decomposition method. The average diameter (D_<av>) of MNPs increased from 6.6 to 12.5 nm with increasing reaction temperature from 200 to 250.C. The heat dissipation efficiency was 22.5 W/g for the MNPs with D_<av> of 12.5 nm, while those with D_<av> of 6.6 nm did not generate any significant heat. The surface modification of amphiphilic co-polymer was applied to disperse MNPs in water and buffer solution.
