Electron transfer path and energy diagram at the designed biotic/abiotic interface. a Electrons are transferred from S. oneidensis outer membrane cytochrome c to the LUMO of the molecular wire embedded in a 2-nm-thick SiO2 membrane and then to the inorganic catalyst layer (SnO2). b Energy levels of outer membrane cytochromes c (red), the PV3 molecular wires (gray), and the SnO2 layer (purple) based on measured values of each component in isolation. When assembled and positively biased in the complete construct, the energy levels of the PV3 wires and SnO2 layer are likely shifted (indicated in black) to more positive potentials
