Molecular Functionalized Electrodes

具有特定功能的分子功能化电极的研究十分活跃，以期将其应用于电催化、电分析、选择性电合成等领域。然而，对这些电极上的基本现象的解释往往没有被触及，因为它们的实际应用是这些研究的主要目的。开展本项目是为了通过各个领域的研究人员的合作，以及实际使用的分子功能化电极的开发，更好地了解分子功能化电极的基本问题。项目成员至少属于以下研究小组之一：(1)基础理论，(2)电极表面的新探索方法，(3)聚合物修饰电极，(4)生物电催化，(5)生物传感器，并在相互协作和讨论的情况下继续进行项目和自己的工作。得到的一些结果是…在本项目举办的两个“分子功能化电极”研讨会上作了更多介绍。第一次是1985年11月16日在京都举行的，共举办了四次讲座，第二次是1986年1月30日在东京举行的，包括八次讲座和一次小组讨论。本项目的报告给出了进一步的结果。这些结果包括：(1)推导了吸附物种相互作用下表面氧化还原反应的电流-电势方程；(2)建立了镜面反射测量在研究玻碳电极上吸附层的适用性；(3)阐明了聚合物膜内电荷传输与其结构的关系；(4)阐明了葡萄糖氧化酶电极中介体的作用，以及启动子在电极界面C型细胞色素的电子转移反应中的作用；(5)发展了光学免疫传感器和ISFET微生物传感器。较少

Researches on molecular functionalized electrodes having specific functionalities have been actively performed with a view to applying these electrodes to electrocatalysis, electroanalysis, selective electro-synthesis, and so on. However, interpretation of basic phenomena at these electrodes are often left untouched because their practical applications are the primary aim of these researches. The present project was undertaken in order to obtain better understandings of the basic problems for molecular functionalized electrodes by the cooperation of rsearchers in various fields, along with the development of these electrodes for practical use. The project members belonged to, at least, one of the following research groups: (1) basic theory, (2) new exploring methods of electrode surfaces, (3) polymer modified electrodes, (4) bioelectrocatalysis, and (5) biosensors, and proceeded to the project and their own work with mutual collaboration and discussion. Some of the results obtained wer … More e presented at the two symposia open to the public on "molecular functionalized electrodes" which were held by this project. The first one was given in Kyoto on November 16, 1985, where four lectures were presented and the second, consisting of eight lectures and a panel discussion, was held in Tokyo on January 30, 1986. Further results are given in the report of the present project. These results include (1) derivation of current-potential equations for surface redox reaction under the effect of interactions of adsorbed species; (2) establishment of applicability of specular reflection measurement to the study of adsorbed layers on glassy carbon electrodes; (3) elucidation of the relation between charge transport within polymer membranes and their structure; (4) elucidations of the role of mediator in glucose oxidase electrode, and that of promoters in the electron transfer reactions of c-type cytochromes at an electrode interface; and (5) development of optical immunosensors and ISFET microbiosensors.
