Interpretation of Mechanochemical Properties of Lipid Bilayer Vesicles from the Equation of State or Pressure−Area Measurement of the Monolayer at the Air−Water or Oil−Water Interface

There are quite a few types of equation of state and abundant π− a curves of various lipid monolayers at the air−water or the oil−water interface in the literature. However, it has been a problem to interpret mechanochemical properties of bilayer vesicles from the π− a information of the monolayer. In fact, even the bilayer surface pressure has not yet been well characterized although the monolaye…
