Topical 3: 2008 Annual Meeting of the American Electrophoresis Society (AES) (T3)

#233 - Nanoscale Electrokinetics I (T3013)
In nanometer-scale systems the electric double layer (EDL) thickness is comparable to characteristic length scale of the system. In these systems the EDLs can overlap and result in anamolous electrokinetic behavior. Recent reports have shown that microfabricated nanoscale systems can be used to sequence DNA, separate and concentrate biomolecules, and act as biological ion channels. This session focuses on theoretical, computational, or experimental studies of natural or engineered systems with nanoscale dimensions which exhibit electrokinetic behavior distinct from their microscale counterparts.
