Ion Channel Based Biosensors: Ionic transport in carbon nanotubes

Joseph S., Mashl R.J., Jacobsson E., Aluru N.R., Beckman Institute of Advanced Science and Technology, US

Transport of molecules through macromolecular pores is of considerable importance in many biological and nano-electromechanical systems. Ion channels found in cell membranes are crucial for shaping electrical signals and controlling flow of ions and fluids [...]

On the Validity of the No-Slip Condition in Nanofluidics

Koumoutsakos P., Jaffe R.l., Werder T., Walther J.H., Swiss Federal Institute of Technology Zürich, CH

In a collaboration with experimental groups at NASA and ETH Zürich we conduct computational studies towards the development of biosensors in aqueous environments. Examples include arrays of carbon nanotubes that may operate as artificial stereocillia [...]

Hydrodynamics of Carbon Nanotubes Contact Angle and Hydrophobic Hydration

Werder T., Walther J.H., Koumoutsakos P., Inst. of Computational Sciences, ETH, CH

Molecular dynamics simulations are used to study the hydrophobic-hydrophilic behavior of carbon nanotubes in water. We report contact angles for tube diameters ranging from 25 to 75 and for droplets containing up to 4632 water [...]

Atomistic Simulation of Electro-Osmosis in a Nanometer-Scale Channel

Freund J.B., University of California at Los Angeles, US

An atomistic simulation of an electro-osmostic flow in a 50 ° A wide channel is performed to examine models for such flows and study its physical details. The working fluid considered is a 1.1M mean [...]
