KSV NIMA’s Langmuir and Langmuir – Blodgett Deposition Troughs are the leading and most widely used instruments for Lanmuir film fabrication, Langmuir film characterization (including microscopy) as well as Langmuir-Blodgett film deposition. 

These are used for the fabrication and characterisation of single molecule thick films that offer precision control over the lateral packing density of molecules.Following characterisation studies of the unique properties of molecules in monolayers, the instruments can also be used to transfer these monolayers using a Langmuir-Blodgett or Langmuir-Schaefer deposition technique. This enables you to create single and multi-layer films with precise control of thickness, molecular orientation and packing density.

The fabrication of insoluble monolayers, at either the gas/liquid or liquid/liquid interface, with controlled packing densities (Langmuir films) and the creation and transfer of such well-ordered functional films to solid surfaces (Langmuir-Blodgett films) find use in a myriad of nanotechnology applications:

  • Biomembranes and molecular interactions
    • Modelling of biological system (e.g. mimicking cell membranes)
    • Chemistry of biologically active molecules
    • Drug delivery and behaviour
    • Immunologic and enzyme-substrate reactions
    • Biosensors and surface immobilized catalysts
  • Organic and inorganic coatings
    • Functional coatings with optical, thermal or conductive properties
    • Protective coatings (e.g. for semiconductors, optics…)
    • Novel coatings with nanotubes, nanowires, graphenes…
    • Smart surfaces
  • Surfactants and colloids
    • Surfactant formulation
    • Colloid stability
    • Emulsions, dispersions, foams stabilization
  • Rheology of thin films
    • Dilational rheology
    • Interfacial shear rheology (with the KSV NIMA Interfacial Shear Rheometer)
