PEI magnetic nanoparticles

Description:
The surface of the super paramagnetic Fe3O4 nanoparticle is covalently functionalized with poly(ethylenimine) (PEI), and has rich amine groups, which can be used for further functionalization. PEI coated magnetic nanoparticles can be used in the area of diagnostic immunoassay, gene transfection, biomolecule separation, cell separation, enzyme immobilization, drug delivery, and biomedical imaging.
