Abstract

We demonstrate that the large field electrophoresis of a single DNA molecule in nanofluidic systems is accompanied by concentration polarization. We illustrate this phenomena by utilizing our electrophoretic simulation tool SIMUL. First we in-vestigate a simple system with univalent strong electrolyte as a bulk solution. Second, a more complicated system with buf-fering background electrolyte is examined. Concentration polarization in the vicinity of the DNA is observed in both the sys-tems. The practical impact of such observations are also discussed.
