Probing the interaction between nanoparticles and lipid membranes by quartz crystal microbalance with dissipation monitoring

open access: yesFrontiers in Chemistry, 2016
There is increasing interest in using quartz crystal microbalance with dissipation monitoring (QCM-D) to investigate the interaction of nanoparticles (NPs) with model surfaces.

Evidence for the Formation of Symmetric and Asymmetric DLPC-DAPC Lipid Bilayer Domains

open access: yesCellular 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

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.

Electrostatics of lipid bilayer bending

open access: yesBiophysical Journal, 1997
The electrostatic contribution to spontaneous membrane curvature is calculated within Poisson-Boltzmann theory under a variety of assumptions and emphasizing parameters in the physiological range. Asymmetric surface charges, either fixed with respect to bilayer midplane area, or with respect to the lipid-water area both induce curvature but of opposite

Cholesterol's location in lipid bilayers [PDF]

open access: yesChemistry and Physics of Lipids, 2016
It is well known that cholesterol modifies the physical properties of lipid bilayers. For example, the much studied liquid-ordered Lo phase contains rapidly diffusing lipids with their acyl chains in the all trans configuration, similar to gel phase bilayers. Moreover, the Lo phase is commonly associated with cholesterol-enriched lipid rafts, which are

Functional tethered lipid bilayers

open access: yesReviews in Molecular Biotechnology, 2000
Our strategy to provide the structural basis for the build-up of functional tethered membranes focuses on three approaches: the first one is based on the pre-organization of a monomolecular layer of a lipopolymer at the water/air interface which is then transferred to a solid support.
