Water-based biocompatible fluid was prepared with magnetite particles (Fe3O4) coated with β-Cyclodextrin via the two-step co-precipitation method. The thermo-magnetic stabilities around induction heating in an alternating current (AC) magnetic field were investigated when the fluid was heated in the AC magnetic field for 900 s
the temperatures of magnetic fluid containing Fe3O4 nanoparticles or Fe3O4/β-Cyclodextrin composite nanoparticles rising to 63 ℃ and 53 ℃ respectively. The hyperthermic tests prove that the magnetic fluid is suitable for localized hyperthermia treatment of cancer.
