Published: Feb. 3, 2022

The Langmuir–Blodgett (LB) technique, through which monolayers are transferred from the air/water interface onto a solid substrate, was first method to allow for controlled assembly of organic molecules. With its almost 100 year history, it has been inspiration most methods functionalize surfaces and produce nanocoatings, in addition serving explore concepts molecular electronics nanoarchitectonics. This paper provides an overview history Langmuir LB films, including potential use devices discussion on why films seldom considered practical applications today. Emphasis is then given two areas where these offer unique opportunities, namely, mimicking cell membrane models exploiting nanoarchitectonics sensors, investigate recognitions, assemble machines. promising topics short- long-term prospects technique also highlighted.
