Abstract: In this work, we reported the investigation on the interaction between DNAstrands self-assembled at gold electrodes and an electron transfer protein, cytochrome c. Weobserved that cytochrome c exhibited well-defined electrochemistry in both double-strandedand single-stranded DNA films. This suggested that the electron transfer reaction ofcytochrome c arose possibly due to the electron hopping along DNA strands rather thanwiring along the double helix. We also compared the heterogeneous electron transfer rate ofcytochrome c with that of a ruthenium complex, which further confirmed this mechanism.
