Langmuir-Blodgett technology membranes

Langmuir-Blodgett Technology and Receptor Action in Stabilized Lipid Membranes... 

Diacetylenes like [30o] after being laboriously prepared, are not polymerized either by heat or ultraviolet irradiation (Iwamura, 1990). Control of molecular packing in crystals is now needed. Introduction of the technology of liquid crystals or Langmuir-Blodgett membranes (Hupfer et al., 1981 Koch and Ringsdorf, 1981) may be of help. 

Langmuir-Blodgett films may have value in many applied areas of traditional interest to the industrial chemist, such as adhesion, encapsulation, and catalysis. The permeability characteristics of monolayer assemblies may also find application as synthetic membranes for ultrafine filtration, gas separation, and reverse osmosis. For example, Albrecht et al. (44) proved the eflSciency of polymeric diacetylene monolayers on semipermeable supports in reducing the flow of CH4. One interesting possibility lies in using LB monolayers as lubricants in magnetic tape technology. Unpublished reports have indicated that frictional coeflScients can be reduced markedly when the tape is coated with a few monolayers. In applications such as those listed previously, difiSculties may well be encountered with the mechanical stability of the films. To date, relatively little research has been carried out in this area. 

The present paper is aimed to construct and characterize the lipid multicomponent films onto a solid surface by a Langmuir-Blodgett (LB) technology. The goal of the work was to compare the interaction of cholesterol or quercetin-3-O-palmitate (Q3P) with membrane lipids at different alcohol concentrations to prove lateral domains formation as a result of molecular association and to understand preferable cholesterol affinity.

Interfaces between aqueous phase and the volumes confined by amphiphilic molecules [288]. In vitro, these refer to lipid vesicles and micelles, lipid lamellae, cubic and hexagonal phases, Langmuir-Blodgett (LB) films, which are important in colloid science and in extraction technology. In vivo, these are the surfaces of biological membranes.
