A simple analytical solution is obtained for the screened Coulombic force between neutral lipid bilayers separated by thin water film within a model formally analogous to the ‘‘spherical model’’ for Ising systems. This model accounts for constraints on the surface charge density fluctuations imposed by the structure of lipid bilayers. The force is attractive at low and repulsive at high temperatures. A relationship between the system parameters and the temperature of the transition from the repulsion to attraction is established. At room temperature predicted force can be repulsive as well as attractive depending on the system parameters and on the assumptions.
