  9. Ion Selectivity in Synthetic and Natural Channels

    31 Mar 2008 | | Contributor(s):: Susan Rempe

    Transport across membranes and nanopores can be characterized by static equilibrium properties as well as by nonequilibrium dynamic properties. For example, equilibrium selectivity properties of a nanopore can be characterized by the difference in interaction free energy for transferring one ion...

    26 Mar 2008 | | Contributor(s):: Michael Colvin

    The past century has seen tremendous progress in determining the biochemical and biophysical processes that constitute life. One exciting consequence of this understanding is the possibility of developing mathematical models of biological function that are accurate and even predictive. My...

  11. Controlling Membrane Organization: Effects of pH, Ions, and composition

    23 Mar 2008 | | Contributor(s):: Jennifer Hovis

    Our main research interests are in determining, at the molecular level, how cell membranes are organized and how that organization relates to function. The primary molecular building blocks of cell membranes are lipids, amphipathic molecules that assemble into two opposed leaflets forming a...

  12. The Functional Protocell concept

    23 Mar 2008 | | Contributor(s):: Eric Jakobsson

    We have invented and created the first prototype of the Functional Protocell.We define the “functional protocell" as a nanoporous solid surrounded by a membrane. The cavities in the solid can be filled with any desired electrolyte up to the limit of solubility. The surrounding membrane can...
