Abstract
Application of magnetic materials for hyperthermia of biological tissue has been known, in principle, for more than four decades. Many empirical works were done in order to confirm a therapeutic effect on several types of tumors by performing experiments with animals or using cancerous cell cultures. The main idea of magnetic nanoparticle (MNP) thermotherapy is to utilize 7- to 50-nm diameter of ferric oxide (Fe3O4)particles which are heated up to 42°C under AC magnetic field for cancer therapy applications. In order to achieve the goal of killing cancer cells using the AC magnetic field, we designed a heating system to generate magnetic field which can be focused and frequency adjustable. This study adopts the half-bridge series-resonant type circuit as the core scheme of the heating system, and utilizes the frequency-adjustable design to conduct the heating experiment. The experiment results show that the designed coil and the heating system can warm up the magnetic nanoparticle 6°C in 32 minutes.
