PLoS ONE, 2015 Supported lipid bilayers are widely used for sensing and deciphering biomolecular interactions with model cell membranes. In this paper, we present a method to form supported lipid bilayers from total lipid extracts of Escherichia coli by vesicle fusion.

Choose your label wisely: water-soluble fluorophores often interact with lipid bilayers. [PDF]
PLoS ONE, 2014 Water-soluble organic fluorophores are widely used as labels in biological systems. However, in many cases these fluorophores can interact strongly with lipid bilayers, influencing the interaction of the target with the bilayer and/or leading to ...

General model of phospholipid bilayers in fluid phase within the single chain mean field theory [PDF]
J. Chem. Phys. 140, 174903 (2014), 2014 Coarse-grained model for saturated (DCPC, DLPC, DMPC, DPPC, DSPC) and unsaturated (POPC, DOPC) phospholipids is introduced within the Single Chain Mean Field theory. A single set of parameters adjusted for DMPC bilayers gives an adequate description of equilibrium and mechanical properties of a range of saturated lipid molecules that differ only in ...

Anomalous diffusion of phospholipids and cholesterols in a lipid bilayer and its origins [PDF]
, 2012 Combining extensive molecular dynamics simulations of lipid bilayer systems of varying chemical composition with single-trajectory analyses we systematically elucidate the stochastic nature of the lipid motion. We observe subdiffusion over more than four orders of magnitude in time, clearly stretching into the sub-microsecond domain.

Elastic Properties of Lipid Bilayers: Theory and Possible Experiments [PDF]
Zeitschrift fur Naturforschung. Teil C: Biochemie, Biophysik, Biologie, Virologie, 1973 A theory of the elasticity of lipid bilayers is proposed. Three types of strain, i. e. stretching, tilt and curvature, are distinguished and the associated stresses are identified.

Water permeation through stratum corneum lipid bilayers from atomistic simulations [PDF]
arXiv, 2009 Stratum corneum, the outermost layer of skin, consists of keratin filled rigid non-viable corneocyte cells surrounded by multilayers of lipids. The lipid layer is responsible for the barrier properties of the skin. We calculate the excess chemical potential and diffusivity of water as a function of depth in lipid bilayers with compositions ...

Flexible Lipid Bilayers in Implicit Solvent [PDF]
, 2005 A minimalist simulation model for lipid bilayers is presented. Each lipid is represented by a flexible chain of beads in implicit solvent. The hydrophobic effect is mimicked through an intermolecular pair potential localized at the ``water''/hydrocarbon tail interface.

Nature Methods, 2021 The quantification of membrane-associated biomolecular interactions is crucial to our understanding of various cellular processes. State-of-the-art single-molecule approaches rely largely on the addition of fluorescent labels, which complicates the ...

Measuring anion binding at biomembrane interfaces
Nature Communications, 2022 Quantification of anion binding by molecular receptors within lipid bilayers is challenging. Here, the authors synthesise a high-affinity macrocyclic anion receptor which provides insights into determinants of anion binding within lipid bilayers.

Water Pores in Planar Lipid Bilayers at Fast and Slow Rise of Transmembrane Voltage
Membranes, 2021 Basic understanding of the barrier properties of biological membranes can be obtained by studying model systems, such as planar lipid bilayers. Here, we study water pores in planar lipid bilayers in the presence of transmembrane voltage.
