Preparation and Characteristic of the New Magnetic Organic-Inorganic Hybrid Molecularly Imprinted Microsphere Materials

摘要

The new magnetic organic-inorganic hybrid composite imprinted microspheres (MHCIM)based on Fe3O4 nanospheres as core structure and imprinted materials as shell structure have been synthesized by surface molecularly imprinted technique using dummy template strategy.Scanning electron microscopy images showed that the MHCIM were with a diameter distribution (10-120 μm)and cross-linking,spherical shape,and porous morphologies.The resultant MHCIM incorporating molecular recognition and magnetic separation properties can provide a highly selective absorbent materials for trace extraction and isolation target molecules from complicated biological matrix.
