The electron transfer reactions of biological molecules are frequently very slow at ordinary electrodes. To overcome this problem, and thus to facilitate the direct coupling of biological redox reactions to electrodes for biosensor or bioelectronic applications, various types of modified electrode have been used. These include electrodes modified by the covalent attachment of species to the surface, by the reversible adsorption of promotors, or by the deposition of polymeric species, and the use of conducting polymers or conducting organic salts as electrode materials. Some of these different approaches are reviewed and their applications to biosensors and bioelectrochemistry are discussed.
生物分子的电子转移反应在普通电极上通常非常缓慢。为了克服这个问题，从而促进生物氧化还原反应与电极的直接耦合以用于生物传感器或生物电子应用，人们使用了各种类型的修饰电极。这些修饰电极包括通过将物质共价连接到表面、通过促进剂的可逆吸附、通过聚合物物质的沉积来修饰的电极，以及使用导电聚合物或导电有机盐作为电极材料。本文综述了其中一些不同的方法，并讨论了它们在生物传感器和生物电化学中的应用。
