Photoelectrochemical properties of pyrene modified DNA immobilized on gold electrode.
Self-assembled monolayers (SAMs) of pyrene-modified DNA were prepared on gold electrode and their photoelectrochemical properties were investigated. The cathodic photocurrent was generated by photoirradiation of the SAM in the presence of methyl viologen as an electron carrier. The photocurrent efficiency increased with increasing the distance between the pyrene and the gold substrate.
