Magnetic nanoparticle response in RF for biomedical applications
To study the RF absorption property of magnetic nanoparticles inside human body, an in vitro technique on tissue equivalent liquid is proposed. Magnetic nanoparticles are used to change the electrical properties of tissue equivalent liquid of 2.10GHz. Effect of short duration of low RF exposure and AC magnetic field is studied to effectively control the specific absorption rate value. Measurement results are reported for particle characterization, dielectric value, electric field strength and specific absorption rate. The studied results anticipates the effective use of magnetic particles for biomedical application, using very low RF power (15dBm) and AC magnetic field of few mT (10–30mT).
