Coatings and thin films made from nanoparticles (NPs) are gaining 
recognition and use in various products and applications including displays, sensors, medical devices, energy storage devices and energy harvesting. Synthesis methods for nanoparticles are already relatively well known, but to be able to utilize them in the applications mentioned above, NPs need to be transferred from the solution phase to a substrate’s surface. For this, controlled deposition methods are required.
This white paper reviews the methods for forming nanoparticle monolayers at the air-liquid interface and their subsequent transfer onto solid substrates using the Langmuir-Blodgett and Langmuir-Schaefer methods.
