The extraction of human genomic information is expected to lead to a revolution in development of individualized medical therapies. Electron transport through DNA-based molecular junctions opens the door to fast and cheap DNA sequencing, on the basis of distinct current–voltage characteristics. This work studies two kinds of sequencing devices with titanium nitride and gold electrodes theoretically. The molecular conductances obtained suggest that these are viable candidate devices for fast DNA sequencing.
