We studied on the development of new modified electrode utilizing electrocatalytic and conducting properties of metal nanoparticles. As the result, unique nano-structured materials, such as gold nanoplates and tripods, could be prepared via wet chemical approaches. In particular, electrocatalytic properties of gold nanoplates were analyzed by modifying them on the electrode surfaces. In addition, in the trials using binary mixture systems of capping reagents for gold nanoparticles, we successfully performed denser and controllable attachments, by which the relationships between surface nanostructures and electrocatalytic properties were clarified. Furthermore, a new three-dimensional modification method of gold nanoparticles was developed.

本论文研究了利用金属纳米粒子的电催化和导电特性制备新型修饰电极。因此，独特的纳米结构材料，如金纳米片和三脚架，可以通过湿化学方法制备。特别地，通过在电极表面修饰金纳米片来分析其电催化性能。此外，在使用二元混合体系的封端剂的金纳米粒子的试验中，我们成功地进行了更密集和可控的连接，其中表面纳米结构和电催化性能之间的关系被澄清。此外，还发展了一种新的金纳米粒子的三维修饰方法。
