Electrochemical impedance spectroscopy as a highly sensitive tool for a dynamic interaction study between heparin and antithrombin: a novel antithrombin sensor.

本文报道了一种用于检测抗凝血酶（antithrombin，AT）的新型生物传感器。作者以肝素作为亲和识别配体，采用硝酸铈铵作为氧化还原引发剂，在硝酸水溶液中使丙烯酸酯单体丁基甲基丙烯酸酯聚合并接枝到肝素多糖上，得到肝素接枝聚丁基甲基丙烯酸酯（PBMA-Hep）共聚物。将该共聚物以薄膜形式沉积在不锈钢316L（SS316L）电极表面，...
