Mechanisms of Electrode Reactions

这个项目是在分析化学和表面化学的一般领域，在机械电化学的子领域。在这项为期三年的持续资助期间，巴德教授和他的学生将对电极反应机制进行广泛定义的基础研究。四个特定的电化学研究重点将继续进行，即(1)生物偶联的电化学研究，特别是小分子与DNA的相互作用；(2)富勒烯修饰电极的电化学和表面性能研究；(3)扫描电化学显微镜在超微电极上快速非均相和均相反应研究中的应用；(4)新型氧化稳定溶剂中电化学反应的研究。这项研究建立在巴德博士之前获得的NSF资助（CHE-8901450）的基础上。除了对非均相电子转移过程的机制提供基本的新见解外，这项研究还与生物传感器的发展以及对新材料和反应化学系统的电化学特性的理解特别相关。

This project is in the general area of analytical and surface chemistry and in the subfield of mechanistic electrochemistry. During the tenure of this three-year continuing grant, Professor Bard and his students will pursue fundamental investigations of electrode reaction mechanisms, broadly defined. Four specific electrochemical research thrusts will be pursued, namely (1) electrochemical studies of bioconjugation, especially the interactions of small molecules with DNA; (2) studies of the electrochemical and surface properties of fullerene-modified electrodes; (3) applications of the scanning electrochemical microscope to the study of fast heterogeneous and homogeneous reactions at ultramicroelectrodes; and (4) studies of electrochemical reactions in novel oxidation-stable solvents. %%% This research builds upon results obtained under Dr. Bard's previous NSF grant, CHE-8901450. In addition to providing fundamental new insights into mechanisms of heterogeneous electron transfer processes, this research is of particular relevance to the development of biosensors and to understanding the electrochemical properties of new materials and reactive chemical systems.
