Abstract

Translocation of DNA through a narrow, single-walled carbon nanotube can be accompanied by large increases in ion current, recently observed in contrast to the ion current blockade. We use molecular dynamics simulations to show that large electro-osmotic flow can be turned into a large net current via ion-selective filtering by a DNA molecule inside the carbon nanotube.
