Abstract
The interfacial direct electron transfer (DET) between a biocatalyst and an electrode is crucial for developing electrochemical devices. Graphene is a promising material for high-performance electrodes because of its electric conductivity, material properties, and low cost. However, the interfacial effect of the oxygen reduction enzyme called laccase (LAC) and graphene has not been studied yet. In this study, immobilization of LAC on graphene results in better DET performance compared to that for previous materials. Moreover, molecular dynamics simulation was performed to visualize the interfacial effects, in terms of the binding site, orientation form, and structural affinity. Graphene and LAC were strongly immobilized by vdW force, and the obtained data were validated by comparison with those of other materials. Our research reveals that immobilization of LAC on graphene results in good DET performance through structural changes of graphene.
