摘  要：
The separation and purification of cells and a variety of biological macromolecules such as nucleic acid,protein are indispensable part of the life sciences.The development of separation and purification technology plays a decisive role for the entire biology.Magnetic microsphere separation is a new type of separation technology based on solid-phase magnetic separation characteristics and integrated biological factors,such as biological molecules and cells.The high-purity target products can be isolated and purified by means of this technology conveniently,quickly and softly.In recent years,magnetic microspheres were progressively applied in many fields,such as biomedicine,cytology and separation engineering.In this paper,the nearly five years of literatures at home and abroad were reviewed in the structure,characteristics and separation principle of magnetic microspheres.The present application situation of magnetic microspheres in cell separation and classification,protein purification,immobilized enzyme,DNA separation and immune analysis and detection were detailedly discussed,and finally the application prospects of magnetic separation technology in of biological purification and detection were summarized.
