Single Electron Switching with Nano-Electromechanical Systems and Applications in Ion Channel Transport
01 Nov 2004 | Online Presentations | Contributor(s): Robert H. Blick
Taking classes in physics always starts with Newtonian mechanics. In reducing the size of the objects considered however the transition into the quantum mechanical regime has to occur. The 'mechanics' of quantum mechanics is best studied in nano-structured semiconductor systems often termed...

Potassium Channels: Conduction, Selectivity, Blockage, Inactivation, and Gating
03 Nov 2006 | Online Presentations | Contributor(s): Benoit Roux, NCN at Northwestern University
The determination of the structure of the KcsA K+ channel fromStreptomyces lividan has made it possible to investigate the functionof a biological channel at the atomic level. Because of its structuralsimilarity with eukaryotic K-channels, investigations of KcsA areexpected to help understand a...

Micro-scaled Biochips with Optically Active Surfaces for Near and Far-field Analysis of Cellular Fluorescence
31 Aug 2007 | Online Presentations | Contributor(s): Huw Summers
The integration of thin (< 100 nm) metal films with micro-scaleoptical waveguides provides a route to controlled spatialexcitation of cellular fluorescence within a biochip platform.Surface bound electron-plasma oscillations (surface plasmon waves)interact with photons to produce an evanescent...

Computing the Horribleness of Soft Condensed Matter
19 Oct 2007 | Online Presentations | Contributor(s): Eric Jakobsson
A great triumph of computer simulations 40 years ago was to make the liquid state of matter understandable in terms of physical interactions between individual molecules. Prior to the first simulations of liquid argon and liquid water in the 1960's, there was no quantitatively rigorous molecular...

Ionic Selectivity in Channels: complex biology created by the balance of simple physics
05 Jun 2008 | Online Presentations | Contributor(s): Bob Eisenberg
An important class of biological molecules—proteins called ionic channels—conduct ions (like Na+ , K+ , Ca2+ , and Cl− ) through a narrow tunnel of fixed charge (‘doping’). Ionic channels control the movement of electric charge and current across biological membranes...
