The ways that redox enzymes communicate with an electrochemical electrode are poorly understood and most systems rely on small molecule mediators as electron shuttles to complete the circuit. The few examples where direct (unmediated) enzyme electrochemistry has been achieved have relied on empirical experimental approaches in electrode modification. In this project a rational approach will be taken, starting with a mediated enzyme electrochemical system which is then systematically deconstructed to produce a minimal enzyme-electrode that is stabilised by non-covalent forces and functions without a mediator. This rational approach will provide new routes to the direct enzyme electrochemistry of other enzyme systems as yet unexplored.

氧化还原酶与电化学电极沟通的方式尚不清楚，大多数系统依靠小分子介质作为电子穿梭器来完成电路。直接（无介导）酶电化学已经实现的几个例子依赖于电极修饰的经验实验方法。在这个项目中，将采取一种合理的方法，从一个介导的酶电化学系统开始，然后系统地解构以产生一个最小的酶电极，该电极由非共价力和功能稳定，没有介质。这种合理的方法将为其他尚未探索的酶系统的直接酶电化学提供新的途径。
