Cholesterol Perturbs Lipid Bilayers Nonuniversally [PDF]

open access: yesPhysical Review Letters, 2008
Cholesterol is well known to modulate the physical properties of biomembranes. Using modern x-ray scattering methods, we have studied the effects of cholesterol on the bending modulus KC, the thickness DHH, and the orientational order parameter Sxray of lipid bilayers.

Confined Multilamellae Prefer Cylindrical Morphology [PDF]

open access: yes, 2005
By evaporating a drop of lipid dispersion we generate the myelin morphology often seen in dissolving surfactant powders. We explain these puzzling nonequilibrium structures using a geometric argument: The bilayer repeat spacing increases and thus the ...

Lipid/water interface of galactolipid bilayers in different lyotropic liquid-crystalline phases

open access: yesFrontiers in Molecular Biosciences, 2022
In this study, carried out using computational methods, the organisation of the lipid/water interface of bilayers composed of galactolipids with both α-linolenoyl acyl chains is analysed and compared in three different lyotropic liquid-crystalline phases.

Formation of unilamellar dipalmitoylphosphatidylcholine vesicles promoted by Ca2+ ions: A small-angle neutron scattering study [PDF]

open access: yes, 2007
Dipalmitoylphosphatidylcholine (DPPC) was hydrated in 0.2-60 mM solution of CaCl 2 in heavy water and thoroughly homogenized by freezing-thawing process.

Correlated diffusion in lipid bilayers [PDF]

open access: yesProceedings of the National Academy of Sciences, 2021
SignificanceDynamic processes on membrane surfaces are essential for biological function. Traditionally, quantitative measurements of lipid/protein motion have been interpreted in the framework of membrane hydrodynamics. However, some recent single-molecule tracking studies have proven difficult to interpret via hydrodynamic arguments.

Electrostatically induced undulations of lamellar DNA-lipid complexes

open access: yes, 2001
We consider DNA-cationic lipid complexes that form lamellar stacks of lipid bilayers with parallel DNA strands intercalated in between. We calculate the electrostatically induced elastic deformations of the lipid bilayers.

Molecular rheometry: direct determination of viscosity in L-o and L-d lipid phases via fluorescence lifetime imaging [PDF]

open access: yes, 2013
Understanding of cellular regulatory pathways that involve lipid membranes requires the detailed knowledge of their physical state and structure. However, mapping the viscosity and diffusion in the membranes of complex composition is currently a non ...
