A Langmuir-Blodgett trough enables the fabrication of single molecule thick layers with control over the packing density onto solid samples. A Langmuir-Blodgett trough consists of a trough, a set of barriers, a surface pressure sensor and a dipping mechanism. The monolayer film is created by adding amphiphilic (polar and non-polar sections) molecules to the surface of the water. The barriers then compress the film to the desired backing density. The monolayer can then be transferred to a surface by dipping the substrate though the film. Multilayer films can be deposited by repeated dipping.

Benefits of the Langmuir Blodgett Trough

Applications in:
– Surface Tension measurements
– Dip coating of substrates for monolayer formation
– Lipid bilayer formation
– Surfactant characterisation
– Drug-membrane studies
– Cell-membrane interactions
