In the laboratory, supported lipid bilayers and monolayers can be made artificially. Such interfacial thin films of nanoparticles have close relationship with Langmuir-Blodgett monolayers made from surfactants. The mechanical properties of nanoparticle monolayers have been studied extensively. Aliphatic thiols form monolayers on gold, which are topical in nanotechnology. These were simple epithelial monolayers with a defined interior and exterior. Hummers graphite oxide is intercalated with two methanol or ethanol monolayers already at ambient temperature. Mechanically exfoliated monolayers of are transparent photovoltaic materials with LED properties. FDTS molecules form self-assembled monolayers. Self-assembled monolayers (SAMs) are formed by chemisorbing reactive reagents with metal surfaces. The classic molecular layer chemistries are self-assembled monolayers (SAMs). One of the common examples of such assemblies are Langmuir-Blodgett monolayers and multilayers of surfactants. However, most electrical devices containing molybdenum sulfide monolayers tend to show n-type behavior. This is due to the two forms of molybdenum sulfide monolayers having different electrical properties. Nanosphere lithography uses self-assembled monolayers of spheres (typically made of polystyrene) as evaporation masks. These reagents used in surface science and nanotechnology to form Self-assembled monolayers.
