Entry needed.


A Langmuir monolayer is a single molecule thick layer of amphiphilic molecules that forms at the interface between air and water. In 1932, Irvine Langmuir won the Nobel Prize in Chemistry for his investigations on the monolayers that bear his name (Reference 1). The general idea is that amphiphilic molecules have a hydrophilic head group and a hydrophilic tail group. The lowest energy conformation has the hydrophilic section sitting just under the water surface with the hydrophobic section sitting just above the water surface into the air.
