Manufacturing ordered films of nanoparticles by Langmuir–Blodgett technique

Abstract The Langmuir–Blodgett (LB) technique is a very convenient tool to build thin films, with sizes that vary from one to a few molecular layers. In general, the technique was applied to amphiphilic molecules that are capable of generating stable Langmuir monolayers at the water/air interface, which can then be transferred to a given solid substrate; however, in recent years, this technique has been expanded to polymers, biomolecules, fullerenes, and nanoparticles. This chapter will attempt to collect the progress in recent years related to the preparation of ordered nanoparticle films using the LB technique. It will aim at different ways of building nanoparticles films that can be used as components of electronic, light emission devices, and chemical or biological sensors.
