ScienceDaily — An electric voltage can be used to propel DNA molecules through a channel a few nanometers deep, or to stop them in their tracks. In a strong electric field the molecules judder along the channel, while in weaker fields they move more smoothly. This enables DNA fragments to be ‘captured’ on a chip and separated for analysis.
