    Simulates ion flow through a channel.

  3. Computing the Horribleness of Soft Condensed Matter

    19 Oct 2007 | | 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...

  4. Discussion about Ion Channels Using Reduced Model Approaches

    21 Sep 2011 | | Contributor(s):: James Fonseca

    The seminar will cover the reasons how the channels are able to selectively permit the flow of certain species of ions while blocking other physiological cations.

  5. From Research to Learning in Chemistry through Visualization and Computation

    17 May 2007 | | Contributor(s):: Eric Jakobsson

    Modern chemistry research and high school chemistry education are separated by institutional and geographical boundaries. As such, much of secondary chemistry education is still based on the periodic table instead of the computational methods that drive current chemistry research. In this talk,...

  7. Illinois iOptics Lecture 1: Super Accuracy and Super-Resolution of Molecular Motors and Ion Channels

    15 Apr 2010 | | Contributor(s):: Paul R Selvin

    The standard diffraction limit of light is about 250 nm, meaning that you cannot "resolve" objects closer than this distance. Despite this, we have come up with a method to measure individual biomolecules with 1.5 nm spatial localization in x-y plane and 1-500 msec temporal resolution, using a...

  8. Ionic Selectivity in Channels: complex biology created by the balance of simple physics

    05 Jun 2008 | | 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 and so play a role in...

  11. P-N Semiconductor Membranes for Ion Filtering and Rectification

    06 Apr 2008 |

    Jean-Pierre Leburton's research at the Beckman Institute deals with transport and optical processes in semiconductor nanostructures such as quantum wires and quantum dots that exhibit a high degree of quantization dependent on the semiconductor materials and geometrical confinement. This...

    04 Apr 2007 | | Contributor(s):: Brian Radak, Hyonseok Hwang, George C. Schatz, Mark Ratner

    This tool simulates ion flow in a system modeled after cyclic peptide ion channels using Poisson-Nernst-Planck (PNP) theory.

  13. Potassium Channels: Conduction, Selectivity, Blockage, Inactivation, and Gating

    03 Nov 2006 | | 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...

    23 Mar 2008 | | Contributor(s):: Vishwanath Jogini

    We are particularly interested in issues about ion permeation, ion selectivity, gating, and channel inhibitors. We are currently working on the KcsA channel, the OmpF porin, and the gramicidin A> channel. We are also spending our efforts in the development of new computational approaches for...
