Surface Pressure

  • Tomohiro ImuraEmail author


The basic concept of the Langmuir–Blodgett trough by measuring the surface pressure of monolayers on water was developed by Irving Langmuir. With this surface pressure measurement, we can evaluate the molecular orientations and interactions of lipids, oils, proteins, and surfactants spreading over liquids as a monolayer. Explorations of the functions of biomembranes utilizing interactions between specific lipid molecules and bioactive molecules at air/water interfaces are research targets based on this technology and are closely related to the advancement of the basics and applications for life science and medical fields. Moreover, the Langmuir–Blodgett film (LB film) as accumulated monolayers on the solid substrate is expected to be a useful module to develop molecular memory or molecular electronic devices.
