In pure water, zwitterionic lipids form lamellar phases with an equilibrium water gap on the
order of 2 to 3 nm as a result of the dominating van der Waals attraction between dipolar …

It was recently demonstrated that significant local deformations of biological membranes
take place due to the fields of charged peptides and ions, challenging the standard model of …

Most lipid components of cell membranes are either neutral, like cholesterol, or zwitterionic,
like phosphatidylcholine and sphingomyelin. Very few lipids, such as sphingosine, are …

When aqueous salt solutions contain multivalent ions (like Ca2+ or Mg2+), strong correlation
effects may lead to ion-bridging, net attraction, and tight-coupling between like-charged …

The interaction between multivalent ions and lipid membranes with saturated tails and
dipolar (net neutral) headgroups can lead to adsorption of the ions onto the membrane. The …

Due to thermal motion and molecular polarizability, electrical interactions in biological
systems have a dynamic character. Zwitterions are dipolar molecules that typically are highly …

Studying lipid monolayers as model biological membranes, we demonstrate that water
molecules interfacing with different model membranes can display preferential orientation …

Electrostatic fields generated on and within biological membranes play a fundamental role
in key processes in cell functions. The role of the membrane dipole potential is of particular …

Dipolar lipid membranes may adsorb multivalent ions. The binding constant depends on the
type of lipid and ions. In this paper, we focus on the adsorption of calcium ions onto 1, 2 …

When two oppositely charged macroions are brought into contact, a large fraction of the
mobile counterions that previously surrounded each isolated macromolecule is released …
