Abstract

The geometrical control of translocation velocity for single DNA molecules in nanoscale space was studied in this paper. We fabricated the nanopore channels which have 250 μm in length, 300 nm in width and 300 nm in depth for confinement of single DNA molecules, and measurement of single DNA molecules translocation velocities. Single DNA molecules translocation velocities in nanopore channels were controlled by fabricating the different nanostructures in front of nanopore channels, such as shallow channels and nanopillars. Based on these strategies, we successfully decreased the single DNA molecules translocation velocities to 7.7 ± 0.8×10-3 cm/s in nanopore channels.
