Monolayers of Poly(ethylene oxide)-Bearing Lipids at Air-Water Interface

Abstract
Monolayers of poly(ethylene oxide)-bearing lipids and their mixed monolayers with dimyristoylphosphatidylcholine at the air-water interface was investigated using surface pressure measurements. The surface pressure-area relationship revealed that the poly(ethylene oxide) moiety length significantly affected the interaction among the lipid molecules. This study provided a precise picture of the lipid membrane-water interface.
