Equilibrium and dynamics of soluble surfactant penetration into a Langmuir monolayer of a 2D aggregating homologue

Article Abstract:

A theoretical and experimental study was conducted that related to research on the use of insoluble-soluble-amphiphile-consisting mixed monolayers to investigate the penetration of insoluble monolayers by a soluble surfactant or protein. The study investigated a simple system consisting of the mixed monolayer of an insoluble, C=20, and soluble, C=12 homologue of dimethylphosphide oxide. It was shown that both the effect of a soluble component on the attributes of the aggregated equilibrium and the effect of the surface pressure increase of the mixed monolayer can be analyzed.

Adsorption from mixed ionic surfactant/protein solutions: Analysis of ion binding

Article Abstract:

A thermodynamic model is derived for the description of the equilibrium behavior of mixtures of a protein with an ionic surfactant adsorbed at the liquid/fluid interface. The experimental data for the mixtures HSA/CTAB (human serum albumin/cetyl trimethylammonium bromide) and beta-LG/SDS (beta-lactoglobulin/sodium dodecyl sulfate) agree satisfactorily with the theoretical estimates.
