Ion channel simulator
4.0 out of 5 stars
14 Feb 2008 | Tools | Contributor(s): David Papke, Reza Toghraee, Umberto Ravaioli, Ankit Raj
Simulates ion flow through a channel.
Computing the Horribleness of Soft Condensed Matter
5.0 out of 5 stars
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...
Discussion about Ion Channels Using Reduced Model Approaches
21 Sep 2011 | Online Presentations | 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.
From Research to Learning in Chemistry through Visualization and Computation
0.0 out of 5 stars
21 May 2007 | Online Presentations | 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...

Illinois iOptics Lecture 1: Super Accuracy and Super-Resolution of Molecular Motors and Ion Channels
16 Apr 2010 | Online Presentations | 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...
Ionic Selectivity in Channels: complex biology created by the balance of simple physics
3.5 out of 5 stars
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...

PNP Cyclic Peptide Ion Channel Model
04 Apr 2007 | Tools | Contributor(s): Brian Radak, Hyonseok Hwang, George C. Schatz, Mark A. Ratner
This tool simulates ion flow in a system modeled after cyclic peptide ion channels using Poisson-Nernst-Planck (PNP) theory.
Potassium Channels: Conduction, Selectivity, Blockage, Inactivation, and Gating
05 Nov 2006 | Online Presentations | Contributor(s): Benoit Roux, NCN SLC@Northwestern
The determination of the structure of the KcsA K+ channel from
Streptomyces lividan has made it possible to investigate the function
of a biological channel at the atomic level. Because of its...
