Abstract: Magnetic nanoparticles with magnetism characteristics and the special performance of nanomaterials,  are widely applied in many kinds of fields. This paper reviewed progress on the magnetic nanoparticles, including types, features, preparation and surface modification. The paper also summarized the latest development of immobilized enzyme technology of lipase, lactase, amylase and a combination of two or more, which was aimed to provide reference for the study of magnetic nanoparticles immobilized enzymes.

Key words: magnetic nanoparticles, lipase, laccase, amylase, immobilized enzymes
