title: Structure orientation of hemin self-assembly layer determining the direct electron transfer reaction.
abstract: We propose a strategy to control directly the orientation of hemin plane via experimental models, Hemin-His model and Hemin-MHN model with ODT. Electrochemical results show that electron communication is largely enhanced when the hemin plane is near to parallel to the electrode surface by histidine ligation in Hemin-His model, while the electron transport of hemin in Hemin-MHN model with ODT becomes relatively difficult.
