Magnetic Beads for Chemiluminescence Immunoassay
In the presence of external magnetic field, magnetic beads exhibit magnetic force and gather, and lose magnetic force and disperse when there is no magnetic field. Active substances such as antigens/antibodies can be combined with active groups on the surface of magnetic beads and coated on magnetic beads by certain methods.

Magnetic Beads
Ferrimagnetic magnetic cores are with over 30 nm relatively large with a strong magnetic moment. They retain this magnetic moment even after removal of the magnetic field. The strong magnetic field leads to a fast separation of the beads in the magnetic field. Possible downfalls are self-magnetism and unwanted attachment to metal surfaces.

Magnetic Immunoassay
Binding of antibody to target molecules or disease-causing organism is the basis of several tests. Antibodies labeled with magnetic nanoparticles give magnetic signals on exposure to a magnetic field. Antibodies bound to targets can thus be identified as unbound antibodies disperse in all directions and produce no net magnetic signal.
