Abstract: Magnetic hydrogel combines the properties and advantages of magnetic material, polymer material and hydrogel into a single platform, which is widely used as biomaterials. Because of their excellent magnetic properties and biocompatibility, magnetic hydrogel can be used as multifunctional drug delivery systems (DDS) for magnetic sensitive drug release, targeting, hyperthermia and magnetic resonance imaging (MRI). In this paper, recent progresses of the preparation and applications of magnetic hydrogel as drug delivery systems are reviewed. And the drug release mechanism of magnetic hydrogel, including the ON/OFF release model and temperature-sensitive release behavior are described in detail.
