Magnetic mesoporous silica nanoparticles (MMSNs) are composite nanoparticles with superparamagnetic Fe₃O₄ as the core and mesoporous silica as the shell. Featuring a highly ordered mesoporous structure, excellent chemical and thermal stability, as well as a surface rich in a large number of easily modifiable hydroxyl functional groups, they are widely used in biomedical fields such as drug carriers, biocatalysis, bioimaging and sensors, disease diagnosis, magnetic resonance imaging (MRI), and intelligent drug delivery.
Functional modification: SiOH、NH2、COOH、PEG、PEI
Size: 80-100nm
