UltraFlex performing induction heating of nanoparticles for medical research

This UltraFlex test application setup confirmed that heating the biological unit containing nanoparticles to the required temperatures could be successfully achieved and that induction heating was the only option to be used.

The successful use of induction to heat injected nanoparticles into biological units has recently been demonstrated by UltraFlex Power Technologies. UltraFlex is a major supplier of advanced digitally controlled induction heaters and its high frequency induction heating equipment is often the preferred choice for research purposes. UltraFlex will design and manufacture the perfect coil to induce the desired field strength or heat for any high frequency application.

In this application case, a Korean science and technology institute specializing in medical research contacted UltraFlex to evaluate the option of heating nano-magnetic material injected into biological units.

Electromagnetic heating of nanoparticles is a process in which external electromagnetic fields interact with the electrical and magnetic properties of nanoparticles. One of the common applications of nanoparticle heating is related to cancer treatment, where high temperature (hyperthermia) is used to destroy tumors.

For this customer scenario, UltraFlex designed a custom inductor, so that the required magnetic field strength of 7.5 kA/m at 570 kHz or 15 kA/m at 350 kHz can be achieved. Magnetic field strength is a key parameter when heating nanoparticles. Therefore, UltraFlex created different simulation setups, based on which the best design for the custom induction coil was determined. The simulations are a complex process with many calculations and measurement procedures, but they confirmed that the designed induction coil could achieve a magnetic field strength of 11 kA/m at 400 kHz with 10% uniformity throughout. of the heating process.

The induction heating equipment used by UltraFlex was their proprietary N-Series Nanoparticle Research System. Nanoparticle Research Systems are ideal for magnetic hyperthermia and other applications. With a variety of power and frequency levels available, these systems will provide the magnetic field strength needed for the customer’s application.

This UltraFlex test application setup confirmed that heating the biological unit containing nanoparticles to the required temperatures could be successfully achieved and that induction heating was the only option to be used. Despite the complexity of this induction heating test setup, it proved the importance of induction heating for medical research. Additionally, induction heating allows for quick and economical setup of research applications, which can often be critical to the success of the final project.
