We have studied the adhesion state (also denoted by docking state) of lipid vesicles as
induced by the divalent ions Ca 2+ or Mg 2+ at well-controlled ion concentration, lipid …

We have used time-resolved small-angle X-ray scattering (SAXS) to study the adhesion of
lipid vesicles in the electrostatic strong-coupling regime induced by divalent ions. The …

Here, we report the first direct observation of Van der Waals' attraction between
biomembrane capsules using measurements of the free energy reduction per unit area of …

We show the existence of a new and unexpected morphology of charged phospholipid
membranes composed of pure dioleoylphosphatidylserine (DOPS, Na+) in the absence of …

Small-angle X-ray scattering and phase-contrast microscopy experiments were performed to
investigate the effect of osmotic pressure on vesicle formation in a …

Cationic, O-alkylphosphatidylcholines, recently developed as DNA transfection agents, form
bilayers indistinguishable from those of natural phospholipids and undergo fusion with …

Parallel fluid membranes in water repel or attract each other and the dependence of the
forces on spacing can result in an equilibrium state of mutual adhesion. Attraction and …

Surfactant bilayers in aqueous media interact non-specifically via long range electrostatic,
electrodynamic, and solvation forces. 1–5 Even though the magnitude of each interaction …

Calculations for the free energy of interaction between phospholipid vesicles have been
performed and applied to the question of vesicle aggregation. Calculations of van der Waals …

Critical to biological processes such as membrane fusion and secretion, ion-lipid
interactions at the membrane-water interface still raise many unanswered questions. Using …
