Nanofluidics: Fundamentals and applications

TRANSDUCERS 2009 - 2009 International Solid-State Sensors, Actuators and Microsystems Conference, 2009
The paper gives a brief overview of nanofluidic theory, with an emphasis on transport processes in nanochannels. It subsequently reports on recent progress in nanofluidic research in the BIOS/Lab-on-a-Chip group, especially DNA electrophoresis in 20-nm high nanoslits, AC electroosmotic flow in nanochannels, and two-phase flow in nano/microfluidic ...

Nanofluidic Diode

Nano Letters, 2007
We present a nanofluidic diode that at voltage range -5 to +5 V rectifies ion current with degrees of rectification reaching several hundreds. The diode is based on a single asymmetric nanopore whose surface was patterned so that a sharp boundary between positively and negatively charged regions is created. This boundary defines a zone that is enriched

Nanofluidic diodes

Chem. Soc. Rev., 2010
Ionic rectifying effect is a unique ion transport phenomenon observed in certain types of nanofluidic devices and cannot be implemented in microfluidics. Analogous to a diode in solid-state electronics, these diode-like nanofluidic devices can be used to turn the ionic flow on and off depending on the polarity of the applied electric-field.
