Abstract

Redox polymers have been widely used to facilitate and stabilize bioelectrochemical communication between the active sites of enzymes and electrodes, enabling development of high-performance enzyme electrodes for sensing, provision of power, and in synthesis. This review offers a brief overview of recent efforts in the use of additional polymer layers on top of a redox polymer/enzyme layer, which can both improve the performance and expand the functionality of the resulting bioelectrodes.
