Kinetics of adhesion of liposomes on mercury electrodes - a biomimetic system to probe membrane stability

The adhesion of liposome on mercury electrodes consists of three steps: the docking of particles on the surface, the opening of the liposome and the spreading of the lecithin island over the mercury surface. This process leads to capacitive signal due to the change of surface charge of mercury under the lecithin layer. The overall process is totally irreversible, but there are some indications that at least the first step could be reversible. Furthermore, the theoretically calculated number of collisions of particles with the surface is higher than the number of signals of the spreading. This can be explained by assuming that some collisions are elastic, while the other are plastic, and that only the latter lead to the spreading.
