Magnetic microparticles and nanoparticles, composed mainly of iron oxides (magnetite, Fe3O4 and maghemite, γ-Fe2O3), can be utilized in various biochemical and biotechnological applications. The particles can be easily manipulated by an external magnetic field. They are frequently used as magnetically responsive insoluble supports for immobilization of biologically active compounds, such as enzymes, antibodies, streptavidin and oligonucleotides. Examples of their applications are presented.
