Amine Functionalized Magnetic Nanoparticles
General Information
These amine functionalized magnetic nanoparticles (dextran coated crosslinked iron oxide nanoparticles (CLIO-NH2)) have 1-3 superparamagnetic Fe3O4 iron oxide cores (8-10 nm in diameter) embedded within the matrix of dextran sugar strands of 40 kDa or 70 kDa size. Dextran strands are crosslinked to prevent their disassociation, ensuring long-term biological stability. Dextran surface has been functionalized with Amine NH2 groups.
