Membrane perturbation by the lipopeptide surfactin and detergents as studied by deuterium NMR

Article Abstract:

Surfactin, much like synthetic detergents, induces imbalances in the lateral pressure between the headgroup and chain region and between the outer and inner lipid layers of the membrane. The structural effects of surfactin on lipid membranes are compared with those of two nonionic detergents by the means of solid-state NMR of selectively deuterated lipids.

Movement of proteins in an environment crowded by surfactant micelles: Anomalous versus normal diffusion

Article Abstract:

Molecular crowding in vitro offers a systematic way to study anomalous and normal diffusion in well-controlled environment not accessible in vivo. The crowded environment in vitro consisting of hexaethylene glycol monododecyl ether ([C.sub.12][E.sub.6]) nonionic surfactant and water and observed lysozyme diffusion between elongated micelles was prepared.

Solvation of octane at water-and methanol-ice surfaces and surfactant effect of methanol at octane-water interface studied by temperature-programmed TOF-SIMS

Article Abstract:

The interaction of octane with water and methanol ice surfaces is investigated. Temperature-programmed TOF-SIMS is used for this purpose.
