The market demand for magnetic microspheres is increasingly strong, and local companies have independent research and development capabilities.

Magnetic microspheres, also known as magnetic beads and magnetic polymer microspheres, refer to composite microspheres with certain magnetism and special structure formed by combining magnetic inorganic particles and organic polymers through appropriate methods. Magnetic microspheres are a new type of magnetic material with the advantages of stable chemical properties, good magnetic responsiveness, and high recovery rate. They are widely used in many fields such as biomolecule detection, cytology, clinical diagnosis, separation and purification, and immune detection.

Preparation methods of magnetic microspheres include monomer polymerization method, embedding method, infiltration-deposition method, co-precipitation method, etc. The monomer polymerization method refers to using acrylic acid, styrene, etc. as active monomers, using magnetic particles, stabilizers, initiators, etc. as raw materials, to obtain finished products through polymerization reactions such as dispersion polymerization and suspension polymerization; the infiltration-deposition method refers to using different ions according to the Bonding groups form coordination bonds with iron salts to prepare magnetic microspheres. This method has the advantages of good finished product quality and easy parameter control. It is expected to become the mainstream preparation method of magnetic microspheres in the future.

The upstream of the magnetic microsphere industry chain is the supply of raw materials, which are usually made of synthetic polymer materials and natural polymer materials, including polyacrylic acid, polystyrene, polyaniline, polyamide, gelatin, cellulose, etc.; the midstream of the industry chain is products Manufacturing, including conjugated magnetic microspheres, coated magnetic microspheres, coupled magnetic microspheres, etc.; the downstream of the industrial chain is application areas, including biomolecule detection, cytology, clinical diagnosis, separation and purification, immunoassay, etc.

According to the “2023-2028 China Magnetic Microsphere Industry Market In-depth Research and Development Prospects Forecast Report released by the Industrial Research Center, In recent years, with the accelerated development of downstream industries, the market demand for magnetic microspheres has become increasingly strong. The global magnetic microsphere market size will reach 10.56 billion yuan in 2022, a year-on-year growth of 26.7%. It is expected that in the future, with the continuous breakthroughs in biomolecule detection, immune detection and other technologies, the market size of magnetic microspheres will further expand and will exceed 15 billion yuan by 2028.

Major global manufacturers of magnetic microspheres include American IGS, American POLYSCIENCES, Dutch Akzo Nobel, American 3M, American Momentive, and Japanese Matsumoto Yushi-Seiyaku) et al. Major players in my country’s magnetic microsphere market include Aladdin, Weston Biotechnology, NanoVis Technology, Jianzhu Biotechnology, etc. NanoVis Technology is a representative enterprise of magnetic microspheres in my country. It has independent research and development capabilities of high-performance magnetic microspheres.

Industry analysts said that magnetic microspheres, as a new type of magnetic material, have broad application prospects in many fields. In recent years, benefiting from the accelerated development of downstream industries, my country’s magnetic microsphere market space has continued to expand. Compared with overseas developed countries, my country’s magnetic microsphere industry started late, but its development momentum is rapid, and local companies have the ability to independently research and develop high-performance products.
