title: Fluidity-dependence of membrane adhesiveness can be explained by thermotropic shifts in surface potential.
abstract: It is demonstrated that the transition of both dimyristoylphosphatidylcholine (DMPC) and dipalmitoylphosphatidylcholine (DPPC) from the gel to liquid-crystalline phase is paralleled by a pronounced increase in the negative surface potential of liposomes composed of either lipid. The Derjaguin-Landau-Verwey-Overbeek (DLVO) theory is applied to show that this phenomenon can serve as a simple explanation of diverse adhesive properties of solid and fluid lipid bilayers.
