Bilayer Edges Catalyze Supported Lipid Bilayer Formation [PDF]
Biophysical Journal, 2010 Supported lipid bilayers (SLB) are important for the study of membrane-based phenomena and as coatings for biosensors. Nevertheless, there is a fundamental lack of understanding of the process by which they form from vesicles in solution. We report insights into the mechanism of SLB formation by vesicle adsorption using temperature-controlled time ...

Volumetric stability of lipid bilayers [PDF]
Physical Chemistry Chemical Physics, 2012 In agreement with recent reports, a commercial densimeter has yielded a gradual decrease in lipid molecular volume of DPPC multilamellar vesicle dispersions in the gel phase upon repeated thermal cycling between 10 °C and 50 °C. The considerable size of this decrease would have significant implications for the physical chemistry of biomembranes.

Composition Fluctuations in Lipid Bilayers [PDF]
Biophysical Journal, 2016 AbstractLipid bilayers constitute the basis of biological membranes. Understanding lipid mixing and phase behavior can provide important insights into membrane lateral organization (the “raft” hypothesis). Here we investigate model lipid bilayers below and above their miscibility transition temperatures.

Evidence for the Formation of Symmetric and Asymmetric DLPC-DAPC Lipid Bilayer Domains
Cellular Physiology and Biochemistry, 2013 Background/Aims: We investigated if mixtures of the phosphatidylcholine (PC) lipids 1,2-dilauroyl-sn-glycero-3-phosphocholine (C12:0 PC; DLPC) and 1,2-diarachidoyl-sn-glycero-3-phosphocholine (C20:0 PC; DAPC), which differ by eight methylene groups in ...

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

Cholesterol Perturbs Lipid Bilayers Nonuniversally [PDF]
Physical 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.

Correlated diffusion in lipid bilayers [PDF]
Proceedings 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.
