Abstract
Entropophoresis - motion caused by an entropy gradient - is a novel nanofluidic method to direct the self-transport of biopolymers that established a new paradigm of nanofluidic functionality with broad relevance to lab-on-a-chip technol-ogy. Here, the entropic effects on size variation of DNA molecules descending a nanofluidic staircase by entropophoresis are studied. A simple numerical model provides insight into the behavior of confined biopolymers - a controversial topic of basic importance in many lab-on-a-chip applications - and informs the rational design and self-operation of nanofluidic devices for future entropophoretic applications, such as the directed self-separation of biomolecular mixtures and directed self-patterning of biomolecular concentration gradients.Proceedings Title
