Counterion-mediated pattern formation in membranes containing anionic lipids

DR Slochower, YH Wang, RW Tourdot… - Advances in colloid and …, 2014 - Elsevier
Most lipid components of cell membranes are either neutral, like cholesterol, or zwitterionic,
like phosphatidylcholine and sphingomyelin. Very few lipids, such as sphingosine, are …

The structure of ions and zwitterionic lipids regulates the charge of dipolar membranes

O Szekely, A Steiner, P Szekely, E Amit, R Asor… - Langmuir, 2011 - ACS Publications
In pure water, zwitterionic lipids form lamellar phases with an equilibrium water gap on the

Two cations, two mechanisms: interactions of sodium and calcium with zwitterionic lipid membranes

M Javanainen, A Melcrová, A Magarkar… - Chemical …, 2017 - pubs.rsc.org
Adsorption of metal cations onto a cellular membrane changes its properties, such as
