IEEE Magnetics Society Seminar on Functional magnetic particles for nanomedicine applications
Magnetic nanoparticles have been building blocks in applications ranging from high density recording to
spintronics and nanomedicine. Magnetic anisotropies in nanoparticles arising from surfaces, shapes and interfaces
in hybrid structures are important in determining the functional response in various applications [1]. In this talk, I
will first introduce the basic aspects of effective anisotropy and measurements through RF transverse susceptibility
experiments. Tuning magnetic anisotropy has a direct impact on the performance of functional magnetic
nanoparticles in biomedical applications such as enhanced MRI contrast and magnetic hyperthermia cancer
therapy. There is a need to improve the surface functionalization and specific absorption rate (SAR) or heating
efficiency of nanoparticles for cancer diagnostics and therapy. Strategies going beyond simple spherical structures,
such as exchange coupled core-shell nanoparticles, nanowire, nanotube geometries can be exploited to increase
saturation magnetization, effective anisotropy and heating efficiency in magnetic hyperthermia. This talk will
combine insights into fundamental physics of magnetic nanostructures along with our recent research advances in
their application in cancer therapy and diagnostics in nanomedicine.
