Thin Solid Films 437:276–279Here we applied the Langmuir-Blodgett technique to align ZnO nanowires between electrodes being two microns apart in a configuration that possess both the quality of single nanowire devices and the advantages of multiple nanowires. We achieved alignment without using lithography, so the procedure is inexpensive and scalable.The Langmuir‐Blodgett (LB) methodology is based on the transfer process of a monolayer adsorbed at the water interface, Langmuir film, from the air‐water interface onto solids by vertical dipping of the substrate immersed on the subphase. The technique allows the continuous variation of material density, packing, and arrangement by compressing or expanding the film by using barriers ...

Langmuir-Blodgett troughs include a set of barriers (2), a Langmuir-Blodgett trough top (3*), a surface pressure sensor (4) and a dipping mechanism (5) as standard. The Langmuir-Blodgett trough top holds the liquid phase and has a well in the center to allow space for solid substrate dipping through the monolayer.25 Mar 1994 Vol 263, Issue 5154 pp. 1726 - 1733 DOI: 10.1126/science.8134836 Abstract The controlled transfer of organized monolayers of amphiphilic molecules from the air-water interface to a solid substrate was the first molecular-scale technology for the creation of new materials.The nanocomposite film comprising of octadecylamine, chitosan, polyvinyl alcohol-silver nanowires and haemoglobin, shortly (OCPAH), was prepared by Langmuir–Blodgett (LB) film deposition techniqu...
A Langmuir-Blodgett trough ( LB trough) is a laboratory apparatus that is used to compress monolayers of molecules on the surface of a given subphase (usually water) and measures surface phenomena due to this compression. It can also be used to deposit single or multiple monolayers on a solid substrate. Description OverviewMethods for synthesis and optimum conditions of the formation of stable water-soluble silica nanoparticles are presented. The silica nanoparticles were synthesized by the hydrolytic polycondensation of tetraethoxysilane using two methods: under alkaline conditions (Stöber´s method) or in an acetic acid medium followed by the …Langmuir 2010, 26, 15680–15685.
