Temperature Increase in Magnetic Nanoparticles by Magnetic Field Induction for Hyperthermia Treatment

The magnetic hyperthermia is a kind of cancer treatment based on heat, induced by magnetic nanoparticles (MNPs). It is considered that the increase of temperature in a range between 42°C to 45°C leads to the suppression of growth of cancer cells and the decrease of tumor. In this work, iron oxide nanoparticles are place in a glass test tube and their heating efficiency was studied. A solution of MNPs are exposed to an alternating magnetic field of 84.86 μT/113 kHz to evaluate experimentally their heating efficiency. The temperature from the MNPs dispersion exhibits strong magnetic susceptibility dependence, with the increase of the magnetic susceptibility of the nanoparticle, the temperature increase is higher, also a dependence of the volume on the increase of temperature was observed.
