Oxygen permeability of fully condensed lipid monolayers

The oxygen permeation resistance of highly condensed monolayers composed of a homologous series of saturated diacyl phosphatidylcholine lipids was measured using a novel technique that combined micromanipulation and electrochemical techniques. The use of lipid monolayer-coated air microbubbles allowed measurement of the oxygen permeation resistance of fully condensed lipid monolayers that were previously unavailable using classical film balance techniques.
