Abstract: | An anthraquinone (AQ) based DNA linker and hairpin-forming DNAs linked by the AQ linker with variable A-T base pairs were synthesized for the investigation of electron transfer through double helical DNA (DNA-ET) in self-assembled monolayers (SAMs). The spectroscopic analysis of absorption spectra indicated that the AQ of the hairpin DNA stacked with adjacent A-T base pair. Electrochemical redox response due to the AQ was observed from the hairpin DNA immobilized on gold electrode, thus the hairpin DNA is suitable for the investigation of DNA-ET in SAMs. |
