Control the movement of a single dsDNA by DEP

In this paper we demonstrate the adoption of both electrophoresis (EP) and dielectrophoretic (DEP) forces to control the movement of a single DNA and stretch this DNA as a stretched bridge across two Al metal electrodes at specific positions. The moving speed of the single DNA molecule can also be manipulated from 0.615 to 2.285μm/s inside a nano-pore region by DEP controlling the opening size of the virtual nanopore. The control of stretched DNA linear structure and moving speed will be the first step toward single DNA base pair detection in rapid nano pore DNA sequencing technology in the future.
