Magnetic Vortex Nanorings: A New Class of Hyperthermia Agent for Highly Efficient In Vivo Regression of Tumors

The unique magnetic vortex structure allows ferrimagnetic vortex-domain iron oxide nanorings to possess negligible remanence and large hysteresis loss, which not only promotes colloid stability but also maximizes the specific absorption rate. It overcomes the super-paramagnetic limitation and allows a new class of nanoparticle agent to be designed for high-performance thermal-based biomedical applications. As a service to our authors and...
