“…Electrochemistry has also been used to study the interaction of liposomes with ions in the aqueous solution. As an example, Karabaliev and others studied the effect of divalent cations of supported lipid membranes using cyclic voltammetry and impedance measurements 84–86 . Measuring the changes of the redox current of electroactive compound in the presence of divalent cations, they were able to describe the effect of such ions on the formation of defects in the membrane.…”

[84][85][86] Measuring the changes of the redox current of electroactive compound in the presence of divalent cations, they were able to describe the effect of such ions on the formation of defects in the membrane. They concluded that the presence of divalent cations stabilizes the supported membrane at negative potentials, preventing the formation of defects.…”

This review aims to summarize the current state of research concerning the interaction of electrodes with liposomes suspended in solutions. Main attention is given to the complex mechanism of adhesion and spreading of liposomes on mercury electrodes. That mechanism can be studied with the help of chronoamperometry, where each adhesion‐spreading event appears as a capacitive current spike. Integration of these spikes produces charge versus time transients that can be modeled and simulated, revealing the details of the multi‐step adhesion‐spreading process. Whereas the number of spikes per time mirrors the macro‐kinetics, the analysis of the time behavior of each spike mirrors the micro‐kinetics of each adhesion‐spreading event. The reviewed studies show that this approach provides a new tool to study the properties of liposome membranes. The adhesion‐spreading of liposomes on mercury electrodes has strong similarities to the process of vesicle fusion, which makes these studies a biomimetic model allowing one to deduce the effects of foreign molecules in bilayer membranes.
