Design of Magnetic Nanoparticles for MRI-Based Theranostics

Magnetic nanoparticles (MNPs) are considered as one of the most developed potential materials in biomedicine. In this chapter, the designing of MNPs for magnetic resonance imaging (MRI)-based theranostics is highlighted. Mechanism for MRI is first introduced, followed by providing some synthetic protocols toward MNPs. Various surface modification techniques are also presented to reach the demand of better MRI-based biomedicine applications. Further theranostic applications of these MNPs are finally discussed including magnetic targeting, controlled drug delivery, magnetic hyperthermia, and controlling of cell fate.
