Grazing incidence X-ray diffraction (GIXD) studies of monolayers of biomolecules at an air–water interface give quantitative information of in-plane packing, coherence length of crystalline domains, etc. Rheo-GIXD measurements can reveal quantitative changes in the nanocrystalline domains of a monolayer under shear. Here, we report GIXD studies of monolayers of alamethicin peptide, DPPC lipid, and their mixtures at an air–water interface under steady shear stress. The alamethicin monolayer and…

Crystallization of Poly(ethylene)s with Regular Phosphoester Defects Studied at the Air–Water Interface
This study demonstrates the formation of Langmuir/LB films from two different PEs with regular phosphoester groups, acting as crystallization defects in the main chain.


Protegrin interaction with lipid monolayers: Grazing incidence X-ray diffraction and X-ray reflectivity study.
The data show that the extent of peptide/lipid interaction and lipid monolayer disruption depends not only on the lipid composition of themonolayer, but the packing density of the lipids in the monolayers prior to the introduction of peptides to the subphase.
Probing the local order of single phospholipid membranes using grazing incidence x-ray diffraction.
The grazing incidence x-ray diffraction measurements of a single phospholipid bilayer at the solid-liquid interface are reported, indicating that the leaflets of the bilayer are uncoupled in contrast to the scattering from free standing phosphatidylcholine bilayers.
Aggregation of a peptide antibiotic alamethicin at the air-water interface and its influence on the viscoelasticity of phospholipid monolayers.
Interfacial oscillatory shear measurements on alamethicin monolayers indicate that its viscoelastic properties are determined by the area fraction of the solid domains, and studies confirm that the vis coelasticity of alamETHicin/phospholipid monolayer is closely related to the alamEthicin-phosphoipid interactions at the air-water interface.
Principles and applications of grazing incidence X-ray and neutron scattering from ordered molecular monolayers at the air-water interface
Abstract The advent of well collimated, high intensity synchroton X-ray sources and the consequent development of surface-specific X-ray diffraction and fluorescence techniques have recently
Interfacial microrheology of DPPC monolayers at the air–water interface
We present systematic measurements of the surface rheology of monolayers of liquid-condensed (LC) dipalmitoylphosphatidylcholine (DPPC) at the air–water interface. Using microfabricated,
Conformation of peptides in lipid membranes studied by x-ray grazing incidence scattering.
The conformation of alamethicin in highly aligned stacks of model lipid membranes by synchrotron-based x-ray scattering is investigated and a pronounced scattering signal is observed in samples of high molar peptide/lipid ratio which is distinctly different from the scattering distribution of an ideal helix in the transmembrane state.
Cholesterol-phospholipid interactions: new insights from surface x-ray scattering data.
We report a structural study of cholesterol-DPPC (1,2-dipalmitoyl-sn-glycero-3-phophocholine) monolayers using x-ray reflectivity and grazing incidence x-ray diffraction. Reflectivity reveals that
Interaction between lipid monolayers and poloxamer 188: an X-ray reflectivity and diffraction study.
The mechanism by which poloxamer 188 seals a damaged cell membrane is examined using the lipid monolayer as a model system, showing that at low nominal lipid density, P188, by physically occupying the available area and phase separating from the lipids, forces the lipid molecules to pack tightly and restore the barrier function of the membrane.
Active microrheology and simultaneous visualization of sheared phospholipid monolayers
A novel technique that combines active microrheology with fluorescence microscopy to visualize fluid interfaces as they deform under applied stress is presented, allowing structure and rheology to be correlated on the micron-scale in monolayer films.
Interfacial shear rheology of DPPC under physiologically relevant conditions.
The obtained dataset and scaling laws enable us to describe the surface viscosity, and its dependence under physiological conditions of DPPC, and the implications on functioning of lung surfactant replacements will be discussed.
