DescriptionThis work studies the interaction of lipid bilayer with hydrophilic silica surface. Main attention is paid to the dependence of the disjoining pressure Π on the distance between the bilayer and the silica substrate h. Π is calculated as a force that compensates the external gravity–type force applied to the bilayer per unit surface area. The dependence of the disjoining pressure on the distance deviated from the expected sigmoidal shape, showing at least two types of stable configurations with negative (attractive) . Structure and the mobility of lipids in the bilayer, as well as the water in the gap between the bilayer and the substrate were characterized by lateral diffusion coefficients, order parameter, hydrogen bond numbers as well as radio and spatial distribution functions.
