Electrostatic properties of model lipid bilayers

From the Baker lab: We are interested in the electrostatic properties of model lipid bilayers. This image shows the results of molecular dynamics simulations on DPPC bilayer systems. Asymmetric surface potentials are induced by Na+ binding to DPPC bilayers surrounded by solutions of (1) 145 mM KCl and 5 mM NaCl and (2) 145 mM NaCl and 5 mM KCl. Na+ ions shown in blue, K+ ions shown in green, and Cl- ions shown in orange.
