Monolayer-protected nanoclusters exhibit good stability both in solution and dry forms and as such are promising materials for nanocircuits and nanodevices. In this article, an efficient method for fabricating 2D crosslinked nanoparticle networks using the Langmuir-Blodgett technique and dithiols as bifunctional linkers is reported. As shown in the Figure, close-packed assemblies are produced.
