[en] The translocation of DNA molecules through nanopores has attracted wide interest for single-molecule detection. However, the multiple roles of electric fields fundamentally constrain the deceleration and motion control of DNA translocation. In this paper, we show how a single anchored DNA molecule can be manipulated for repeated capture using a transmembrane pressure gradient. Continuously and slowly changing the magnitude of the pressure provided two opposite directions for the force field inside a nanopore, and we observed an anchored DNA molecule entering the nanopore throughout the process from tentative to total entry. The use of both voltage and pressure across a nanopore provides an alternative method to capture, detect and manipulate a DNA molecule at the single-molecule level. (paper)
