| 英文摘要 | molecular imprinting as a promising and facile separation technique has received much attention because of their high selectivity for target molecules. in this study, the superparamagnetic lysozyme surface-imprinted polymer was prepared by a novel fabricating protocol, the grafting of the imprinted polymer on magnetic particles in aqueous media was done by atom transfer radical polymerization (atrp), and the properties of the imprinted polymer were characterized in detail. its high selective adsorption and recognition to lysozyme demonstrated the separation ability of the magnetic imprinted material to template molecule, and it has been used for quick and direct separation of lysozyme from the mixture of standard proteins and real egg white samples under an external magnetic field. furthermore, the elution of lysozyme from the imprinted material was achieved by peg/sulphate aqueous two-phase system, which caused lysozyme not only desorption from the imprinted materials but also redistribution in the top and bottom phase of aqueous two-phase system. the aqueous two-phase system exhibited some of the extraction and enrichment effect to desorbed lysozyme. our results showed that atrp is a promising method for the protein molecularly imprinted polymer preparation.
