Schematics of the MD simulation: SWCNT is connecting two reservoirs with solvated KCl; the system is embedded in electrophoretic field Eext; besides the fixed surface charge, CNT also contains mobile surface charges, to allow for the CNT polarization in the field. (a) Ionic current flows through CNT; (b) The ionic current while DNA is translocated through the CNT.
