A system of two planar bilayers holds a special place among the models employed for
investigating the mechanisms of membrane fusion. This is due to the fact that only this
system makes it possible to investigate the elementary acts of interaction of single lipid
bilayers. The present review is devoted only to the description of experimental and
theoretical results obtained using this model. After a brief introduction, we describe the
experimental system and those methods which are employed for its study. Next, we analyze …
