Probing DNA sequences by anthraquinone-modified DNA that is immobilized on gold surface.
2'-Anthraquinone-modified oligonucleotide (AQ-ODN) possessing disulfide terminus has been immobilized on the gold electrode surface. The AQ-ODN-modified electrode showed faster electron transferability in double-stranded form than that in single-stranded form.
