Periodic arrays of micro‐ or nanopillars constitute solid‐state matrices with excellent properties for DNA size separation. Nanofabrication technologies offer many solutions to tailor the geometry of obstacle arrays, yet most studies have been conducted with cylinders arranged in hexagonal lattices. In this report, we investigate the dynamics of single DNA collision with elliptical nanoposts using hydrodynamic actuation. Our data show that the asymmetry of the obstacles has minor effect on… 

Confinement and partitioning of a single polymer chain in a dense array of nanoposts.

A Brownian dynamics simulation study on the confinement and partitioning of a single, flexible polymer chain in a dense array of nanoposts with different sizes and separations finds that the non-monotonic dependence of the chain elongation results from an interplay between the confinement-drivenchain elongation along the direction parallel to the nanopostS and the chain spreading perpendicular to the Nanosts by partitioning chain segments over several interstitial spaces.

It is shown that in the simplest situation with one type of particles only, this model is exactly soluble, and enhanced mean-field approximation as well as direct numerical simulations are used.

Confinement-driven organization of a histone-complexed DNA molecule in a dense array of nanoposts.

The first step in the controlled storage of lengthy DNA molecules is to keep DNA molecules separated while integrated in micrometer-sized space. Herein, we present hybrid Monte Carlo simulations of a



Hydrodynamic manipulation of DNA in nanopost arrays: unhooking dynamics and size separation.

This study defines experimental conditions for the efficient separation of DNA fragments of tens of base pairs, and provides a complete framework by which to understand the behavior of DNA in the course of hydrodynamic-driven migrations through nanopost arrays.

Electrohydrodynamic Stretching of DNA in Confined Environments

The effect of confinement on the dynamics of polymers was studied by observing the transient extension and relaxation of single DNA molecules as they interacted with obstacles in a specially designed

Statistical properties of the electrophoretic collision of a long DNA molecule with a small obstacle

The authors' experiments provide insights into a regime that is very challenging for numerical simulations but highly relevant for separation processes, indicating that 350 nm is still well above the point‐sized limit.

Electrophoretic collision of a DNA molecule with a small elliptical obstacle

A Brownian dynamics study of the collision and unhooking of a λ‐DNA molecule with an elliptical obstacle finds that elliptical obstacles should be less effective than cylindrical obstacles for DNA separations based on hairpin formation.

DNA electrophoresis in microlithographic arrays

Observations using epifluorescence microscopy of the electrophoresis and length fractionation of large DNA molecules confined in arrays are reported using optical microlithography to fabricate capped quasi-two-dimensional obstacle courses in SiO2.

Effects of embedded sub‐micron pillar arrays in microfluidic channels on large DNA electrophoresis

The consequence of these additional influences implies a complexity in the measured DNA velocity and indicates that careful considerations have to be taken when these devices are used for DNA electrokinetics study or electrophoresis theory re‐examination.

Separation of long DNA molecules by quartz nanopillar chips under a direct current electric field.

It is demonstrated that, even under a dc electric field, the optimal nanopillar dimensions depend on a gyration radius of DNA molecule that made it possible to separate large DNA fragments in a short time.
