The surface of 20 nm Fe₃O₄ nanoparticles contains active functional groups, making them suitable for covalent conjugation with proteins (antibodies, streptavidin, Protein A, Protein G, etc.) or other biomolecules (biotin, glutathione). In addition, dextran-modified Fe₃O₄ nanoparticles exhibit superparamagnetism and magnetic responsiveness. This type of magnetic nanoparticle can be separated using magnetic separation columns, offering simple operation and excellent suspension stability in different buffer solutions, which effectively ensures efficient antibody conjugation, high resistance to nonspecific adsorption, reaction uniformity, and consistent detection performance. They are suitable for biomedical applications such as magnetic targeting, magnetic hyperthermia, T2-weighted imaging, and cell sorting.
