Progress in the preparation and application of core-shell magnetic polymer microspheres (A review);

Using PEG as the dispersant,the core-shell composite magnetic polymer microspheres with hydroxy groups,were synthesized by dispersion copolymerization of styrene and glycol monoacrylate in the presence of magnetic oxide and characterized by X-ray diffraction,transmission electron microscope,scan electron microscope,FTIR spectroscopy etc.

Recently, there have been increasing interests for the research to so-called magnetic polymer microspheres because of their various functionalities.

Using BPO as the initiator, the core-shell composite magnetic polymer microspheres with carboxyl groups, were synthesized by dispersion copolymerization of styrene and acrylic acid in the presence of magnetic oxide and characterized by X-ray diffraction, transmission electron microscope, scan electron microscope, FTIR spectroscopy etc.

New separation technologies such as reversed micelles and magnetic polymer microspheres for application in nattokinase were put forward in order to improve its purity and yield.

Developed in the mid-1980s, magnetic polymer microsphere cut across many areas such as materi- als,biology and immunoassay.

The preparation and utilization of magnetic microspheres;

In this paper recent research on magnetic microspheres is reviewed from several aspects ,includ-ing their preparation methods,structure,properties and applications.

P(St-GMA-DVB) polymer magnetic microspheres were synthesized by suspension polymerization method.

Methods of preparation, structure and characterization of biopolymer magnetic microsphere in enzyme immobilization, drug targeting, cell separation and immunoassay was also briefly covered.
