Magnetic Fluid Hyperthermia

Magnetic Fluid Hyperthermia

Magnetic nanoparticles are not only used in micro- and nanorobots but also play a key role in magnetic fluid hyperthermia. When an alternating magnetic field is applied, interactions between the particles and their surrounding medium generate heat, typically raising the local temperature to between 42 and 45 °C. This targeted heating enables a variety of promising therapeutic applications. For example, it can be used to selectively destroy cancer cells, or to trigger drug release from materials that respond to specific temperatures—ensuring precise delivery at the site of disease. The generated heat can also help disrupt bacterial biofilms and eliminate infection reservoirs. A major advantage of this technique is its localized effect: only the affected tissue is heated, while the surrounding healthy tissue remains largely unharmed. At our institute, we are actively working to optimize the hyperthermic properties of magnetic nanoparticles and explore new application scenarios with the potential to enhance existing therapies or pave the way for entirely new treatment strategies.
