Deposition of Thin Lipid Films Prepared by Electrospraying

Food and Bioprocess Technology, 2012
An efficient way to apply coatings on complex surfaces is electrospraying. We report on coating of porous model surfaces with well-defined properties using a multiple nozzle electrospraying system to spray sunflower oil and butter-based coating materials. Selected model surfaces were nickel membranes with large rectangular straight-through pores (13 μm

Pulsed Plasma Deposited Maleic Anhydride Thin Films as Supports for Lipid Bilayers

Langmuir, 2000
Pulsed plasma polymerization has been used to deposit thin polymer films from maleic anhydride. By variations of the duty cycle (ton/(ton + toff)) employed during the plasma treatment, it has been possible to achieve a high retention of the anhydride groups within the film.

Langmuir — Blodgett deposition of lipid films on hydrogel as a basis for biosensor development

Analytica Chimica Acta, 1985
Abstract Lipid membranes composed of phosphatidyl choline and cholesterol were interfaced to polyacrylamine hydrogen by Langmuir—Blodgett thin-film deposition. The extent of lipid adsorption to the gel surface was critically dependent on the hydration of the polymer as determined by contact angle measurements.

Functionalisation of Si/SiO2 and glass surfaces with ultrathin dextran films and deposition of lipid bilayers

Biosensors and Bioelectronics, 1996
Dextran with molecular weight of 500 kDalton was covalently coupled to glass and Si/SiO2-surfaces by epoxy functionalisation or by photo reactive functionalisation of the solid surface. With the described methods we can control the deposited mass density between 0.3 and 4.8 ng/m2 corresponding to mean film thicknesses of a dry dextran film between 2 A ...

Spectroscopic studies of membrane protein-lipid bilayer systems deposited on multilayer thin film coatings

Optical Interference Coatings, 1997
Although thin film coatings have been used for many years in optical investigations of biological systems (especially as narrow band light filters), more recent applications of such films in two types of spectroscopic devices, surface plasmon resonance (SPR) and optical waveguides, have provided new biophysical tools for the study of protein-protein ...

Investigation of Specific Binding of Antifluorescyl Antibody and Fab to Fluorescein Lipids in Langmuir-Blodgett Deposited Films Using Quartz Crystal Microbalance Methodology

Analytical Chemistry, 1994
Antifluorescyl IgG antibody and Fab binding to two fluorescein-conjugated lipids was measured using the quartz crystal microbalance methodology. By use of the Langmuir-Blodgett technique, the fluorescein lipids, which were diluted to 5% in a L-alpha-dipalmitoyl phosphatidylethanolamine (DPPE) matrix, were deposited directly onto one gold electrode of ...

The deposition of Langmuir-Blodgett films containing purple membrane on lipid- and paraffin-impregnated filters

Thin Solid Films, 1983
Abstract Langmuir-Blodgett films containing the light-driven proton pump, bacteriorhodopsin, in the form of purple membrane were deposited onto cellulose ester filters previously impregnated with hexadecane and soya lecithin. The effect of the K+-selective ionophore, valinomycin, on the photopotential generated across these combined films was ...

Electrochemistry of α-Tocopherol (Vitamin E) and α-Tocopherol Quinone Films Deposited on Electrode Surfaces in the Presence and Absence of Lipid Multilayers

The Journal of Physical Chemistry C, 2009
Water insoluble α-tocopherol films were deposited on the surface of gold, glassy carbon and platinum electrodes and their voltammetric behavior examined in aqueous solutions between pH 3 and 13. The voltammetric mechanism involved α-tocopherol being oxidized in a −2e−/−H+ process to form a phenoxonium cation, which underwent rapid reaction with water ...

Application of Langmuir-Blodgett Technique for Depositing Thin Films of Lipids from Archaebacterium

1996
Extremophilic micro-organisms, Archaea in particular, have been the objects of intense studies (Kandler, 1992) because they grow in unusual habitats. Archaea, a phylogenetically coherent separate group different from Eubacteria and Eukarya, comprises a variety of extremophilic bacteria which live segregated into a few peculiar ecological niches ...

Spoilage of hydrogel contact lenses by lipid deposits. Tear-film potassium depression, fat, protein, and alcohol consumption.

Ophthalmology, 1988
"Jelly-bump" deposits, which are composed mainly of lipids, on high water content, extended-wear hydrogel lenses, are a clinically significant problem of unknown etiology. The authors explored the effect of nutrition on the frequency of deposition of these jelly bumps.
