Magnetics Lab
Magnetic nanoparticles (MNPs) can interact with alternating magnetic fields (AMFs) to deposit localized energy for hyperthermia treatment of cancer. Hyperthermia is useful in the context of multimodality treatments with radiation or chemotherapy to enhance disease control without increased toxicity. Specific loss power (SLP), which is used to quantify the nanoparticles’ heat generation under an applied AMF, is defined as the thermal power per unit mass dissipated by the magnetic material. Accurate measurement of energy dissipation in magnetic nanoparticle suspensions is necessary for evaluating the performance of different material systems and for enabling comparisons with theoretical models. SLP is identified at 150-350 kHz and 10-30mT through the suspension's temperature rise measured by optical fiber sensors.
