Langmuir-Blodgett Films are thin layers of material created by transferring molecules from a liquid surface onto a solid substrate. This process involves spreading a monolayer of molecules on the surface of water, where they arrange themselves due to interactions like van der Waals forces. The film is then transferred to a solid surface by lowering the substrate into the water. These films can be made from various materials, including lipids and polymers, and are used in applications such as sensors, optics, and electronics. The ability to control the thickness and composition of the films makes them valuable for research and industrial purposes.
