Membranes prepared by the adsorption of phospholipid vesicles on solid supports are much-used model systems in biomedical research. However, there is accumulating evidence that such membranes may not always be equivalent to the free-standing cellular membranes that they are modeling. In the present study, sonicated DOPC/DOPS (80/20 mol %) vesicles were adsorbed on hydrophilic silica surfaces, a system that has been demonstrated to produce confluent bilayers. In addition, pure DOPC and DLPC membranes were studied. It is demonstrated that ethanol-induced membrane interdigitation, as demonstrated for free-standing bilayers, does not occur in these supported membranes.
