While most of these applications are sensing-oriented, my research focuses on microwave actuation, particularly heat generation. It enables a novel non-invasive approach for applications such as tumor ablation and neural stimulations. A variety of techniques have been employed to raise the local temperature for these emerging biomedical applications including dielectric heating and ohmic heating. However, they suffer from poor material specificity and undesired damage to the surrounding tissues. Our key idea is to explore magnetic heating induced by magnetic nanoparticles (MNP) which offers superior heating specificity. We proposed and demonstrated a miniaturized microheater array utilizing ferromagnetic resonance of the MNP at GHz to enable localized yet accurate temperature manipulation in living cells and tissues.application/pdfengCopyright is held by the author, unless otherwise indicated.
