本文利用直接法将此复合物滴涂于洁净的玻碳电极(GCE)表面,在其复合膜表面固定纳米铂(nano-Pt)并吸附癌胚抗体(anti-CEA),通过抗体与抗原特异性反应,HRP与H_2O_2之间的电流响应,采用循环伏安法(CV)表征该免疫传感器的制备过程。结果表明,本文制备的免疫传感器操作简单,检测快速,灵敏度高等等,实现了对CEA的定量分析提供参考依据。 In this paper, the composite was directly applied to the surface of clean glassy carbon electrode (GCE) by direct method. The surface of the composite membrane was fixed with nano-Pt and the anti-CEA was adsorbed. Sexual response, current response between HRP and H_2O_2, and the preparation of the immunosensor was characterized by cyclic voltammetry (CV). The results showed that the immunosensor prepared in this paper was simple, rapid, sensitive and so on, which provided a reference for the quantitative analysis of CEA.
