Abstract

Electron transport through DNA-based molecular junctions opens a door for fast and cheap DNA sequencing. The sequence of DNA can be identified according to its distinct current–voltage characteristics. This can be achieved by using titanium nitride as an electrode in the molecular junction, as presented by Xiang Chen on page 2295. Rapid DNA sequencing is able to provide abundant information on the human genome and may lead to a revolution in medical care.
