中文摘要fourier transform surface plasmon resonance (ft-spr) was utilized to study specific and non-specific interactions between proteins and a biotinylated polymer film by monitoring adsorptions of streptavidin (sav) and bovine serum albumin (bsa) on the polymer films. the biotinylated polymer, poly(lactide-co-2,2-dihydroxymethyl-propylene carbonate-graft-biotin) [p(la-co-dhc/biotin)], was prepared by ring-opening copolymerization of lactide and a oh-bearing cyclic carbonate monomer, followed by biotinylation of the oh groups. the copolymer was coated onto the ft-spr chip and vacuum-dried, hydrated at 70 degrees c, and treated with a blocking agent respectively to achieve different surface status. the ft-spr results showed that the vacuum-dried film had the most bsa adsorption; hydration treatment led to migration of the biotin moieties from inner film to surface and thus resulted in less bsa adsorption; blocking layer on the polymer surface saturated the active sites for physical and chemical adsorptions on the surface and thus weakened the bsa adsorption. adsorption of sav displayed similar polymer-surface-status dependence, i.e., more adsorption on vacuum-dried surface, less adsorption on hydrated surface and the least adsorption on blocked surface. compared with bsa, sav showed more enhanced adsorptions on p(la-co-dhc/biotin) surface because of the specific interaction of biotin moieties in the polymer with sav molecules, especially on the blocked surface. the above semi-quantified results further indicate that the ft-spr system is suitable for investigating interactions between polymer surface and bio-molecules.
