Aminated magnetic microspheres

Aminated magnetic microspheres are superparamagnetic magnetic particles with amino functional groups modified on their surface, widely used in biomedical and molecular biology research. This 1μm aminated magnetic microsphere is composed of polystyrene and nano-iron oxide, exhibiting hydrophilicity and good biocompatibility. The aminated magnetic microspheres possess superparamagnetism, fast magnetic response, good monodispersity, ensuring reaction uniformity and detection consistency. The unique rough surface structure and polymer modification give the aminated magnetic microspheres a high amino density, allowing them to covalently couple with bioligands such as peptides, proteins, oligonucleotides, drug molecules, and glycoproteins through the action of special chemical reagents (such as glutaraldehyde). They serve as excellent coating materials and are important carrier tools in medical and biomolecular research.
