Dynamics of the refractive index in Langmuir monolayers
The European Physical Journal E, 2022We present theoretical description of dynamics of the refractive index in Langmuir monolayers subjected to continuous-wave (CW) laser radiation, using the mechanism of the local temperature fluctuations. Such mechanism can be applied to all monolayer systems that consist of rodlike molecules. The CW laser radiation induces conformational transitions of

Phase transition in Langmuir monolayers
Colloids and Surfaces A: Physicochemical and Engineering Aspects, 2001Abstract The main features of several theoretical models which describe the main phase transition and correspondingly the non-horizontal shape of the Π-A isotherms of the Langmuir monolayers, are discussed. New equations of state are based on the generalised Volmer's equation and consider the coexistence monomers and large clusters as bimodal ...

Phage Langmuir monolayers and Langmuir–Blodgett films
Colloids and Surfaces B: Biointerfaces, 2011Stable, insoluble Langmuir monolayer films composed of Staphylococcus aureus-specific lytic bacteriophage were formed at an air-water interface and characterized. The phage monolayer was very strong, withstanding a surface pressure of ∼40 mN/m at 20 °C.

From Langmuir Monolayers to Multilayer Films
Langmuir, 2016This feature article is intended to describe a route from Langmuir monolayers as the most suitable and well-defined models to polyelectrolyte multilayers. The latter are structurally controlled not with angstrom but with nanometer precision; however, they are very modular with regard to building blocks and function and are robust, therefore promising ...

Buckling of Langmuir Monolayers
Europhysics Letters (EPL), 1989We show that under compression on a Langmuir trough, a surfactant monolayer may have a mechanical instability similar to the buckling instability of a beam or a plate. In the buckled state, the wavelength of the surface undulations is the capillary length resulting from the balance between gravity and curvature energy and is in the range of 104 A.

Photosystem I in Langmuir–Blodgett and Langmuir–Schaefer Monolayers
Langmuir, 2012Photosystem I (PSI) is a membrane protein complex that generates photoinduced electrons and transfers them across the thylakoid membrane during photosynthesis. The PSI complex, separated from spinach leaves, was spread onto the air-water interface as a monolayer and transferred onto a gold electrode surface that was precoated with a self-assembled ...

Langmuir and Langmuir−Blodgett Monolayers of Molecular Tweezers and Clips
Langmuir, 2007Molecular clips and tweezers are able to selectively bind electron-deficient aromatic and aliphatic substrates. By means of pressure-area isotherms and Brewster angle microscopy (BAM), the self-association process and phase behavior of dimethylene-bridged molecular clips and tetramethylene-bridged molecular tweezers each substituted with two acetoxy ...

Interfacial polymerisation of anilinium at Langmuir monolayers
Chemical Communications, 2004Anilinium is strongly adsorbed at monolayers of the phospholipid L-alpha-dimyristoylphosphatidic acid (DMPA) and hexadecanesulfonic acid (HDSA) at the air-water interface, and undergoes chemical polymerisation under conditions where bulk polymerisation does not occur.

Molecular recognition at Langmuir monolayers
Current Opinion in Chemical Biology, 2006In the field of chemical biology, molecular recognition has served as a basic concept to understand the construction of biological assemblies and the biological functions. Among the model systems available to investigate 'lock and key' interactions, the interfacial molecular recognition at the air-water interface is an appropriate system because it ...

Structure and phase transitions in Langmuir monolayers
Reviews of Modern Physics, 1999Lipid monolayers on the surface of water have been studied for over a hundred years, but in the last decade there has been a dramatic evolution in our understanding of the structures and phase transitions of these systems, driven by new experimental techniques and theoretical advances.
