Abstract

Direct electrochemistry of redox proteins provides exciting platforms for performance improvement of biosensors and power enhancement of biofuel cells. Nanomaterials with tailored structures and unique properties are promising building blocks to promote direct electron transfer (DET) between redox-active cofactors of proteins and electrodes. This paper reviews the advances of nanostructured materials for DET of redox proteins in recent years, and is divided into applications in biosensors and biofuel cells. Both of them focus on the performance improvement, together with discussion on major challenges and opportunities for future research. The enhancement mechanism for direct electrochemistry is also reviewed for fundamental insights.
