| 英文摘要 | In this work, we describe a method of constructing a film of linear poly(glycidyl methacrylate) (PGMA) polymer onto the surface of quartz crystal microbalance (QCM) electrode as a coating material that allows easy coupling of heparin molecules onto the electrode and facilitates the determination of the interaction between heparin and antithrombin III (AT III). The PGMA film was characterized with atomic force microscopy (AFM) and infra-red spectroscopy. The coupling of heparin was accomplished in one step solution reaction. A home-made quartz crystal microbalance-flow injection analysis (QCM-FIA) system with data analysis software developed in our laboratory was used to determine the interaction. The interactions between immobilized heparin and AT Ill were studied with various concentrations under various conditions. The obtained constants are k(ass) = (1.49 +/- 0.12) x 10(3) Mol(-1) 1 s(-1), k(diss) = (3.94 +/- 0.63) x 10(-2) s(-1), K-A = (3.82 +/- 0.33) x 10(4) mol(-1)l. (c) 2004 Elsevier B.V.
