Abstract

L10-phase iron-platinum (FePt) nanoparticles (NPs) are an excellent magnetic material which is expected to be utilized for ultra-high density magnetic storage media because of their superior magnetic properties. Meanwhile, fcc-phase FePt NPs are also expected to be a high-performance nanomagnet for magnetic medicine, including magnetic hyperthermia, magnetic resonance imaging, magnetic cell/protein/organelle separation and magnetofection, because they present a superparamagnetic behavior with high saturation magnetization and high chemical stability. We outline the effectiveness of fcc-phase FePt NPs for some medical applications in comparison to superparamagnetic iron oxide (SPIO) NPs. In addition, some recent developments regarding magnetic-fluorescent and magnetic-plasmonic dual functional core-shell NPs are presented.
