Abstract Magnetic Fe3O4/mesoporous silica (Fe3O4/mSiO2) composite microspheres combine the advantage of magnetism performance of Fe3O4 nanoparticles and the space loading capacity of mesoporous silica, which therefore are widely explored for uses in biomedicine. In this paper the synthetic methods of Fe3O4/mSiO2 composite microspheres such as core-shell type, hollow type and rattle type were introduced. The applications of Fe3O4/mSiO2 composite microspheres in targeting drug-loading system, magnetic resonance imaging (MRI), magnetic mediated hyperthermia drug-loading system and biological separation are summarized as well.
