Abstract

A 25 s separation of DNA fragments (48.5 and 1 kbp fragments) was achieved by a nanowall array structure, although the separation of 1 kbp and 100 bp DNA fragments was not. Direct observation of a single DNA molecule indicates that it takes over 20 s for an elongated DNA molecule to relax inside the nanowall array structure. Numerical fitting of DNA molecular dynamics reveals that the balance between times for the transverse of an elongated DNA molecule and the relaxation process of a DNA molecule inside the nanowall array structure governs the separation of DNA.
