Detecting DNA Using a Single Graphene Pore by Molecular Dynamics Simulations
DNA charged negatively could be transported through a solid nanopore by the force of an electrical field. Recently, the nice properties of graphene attract a lot of researchers. In this paper, A single graphene membrane was punched to form a nanopore and a ds-DNA was driven to pass through the pore by all-atom molecular dynamics simulations. The single graphene membrane was demonstrated useful in DNA sequencing. It suggested that the velocity of DNA translocating through a single graphene pore could be controlled by adjusting the appropriate voltage and the diameter of the nanopore.
