Magnetic mesoporous silica nanoparticles are a series of composite nanoparticles with superparamagnetic Fe3O4 as the core and mesoporous silica as the shell. They have highly ordered mesoporous structure, good chemical and thermal stability, and a large number of easily modified hydroxyl and amino functional groups on the surface. They are widely used in biomedical fields such as drug carriers, biocatalysis, bioimaging and sensors, disease diagnosis, magnetic resonance imaging, and intelligent drug release.
