Measurements and Modeling of the Failure Pressure of Bilayer Lipid Membranes
Bilayer lipid membranes (BLMs) are formed from phospholipid molecules which self-assemble into a lipid bilayer with 4 to 9 nm thickness when submerged in an aqueous solution. This is due to their amphiphilic nature, meaning that one part of the molecule is hydrophilic, or attracted to water, and …

Biomembranas formuojančių monosluoksnių ir adsorbuotų biomolekulių struktūros tyrimas virpesinės spektroskopijos metodais /
… practical importance. Here we analyze tethered bilayer lipid membranes (tBLM) and laccase enzymes at the electrode surface in water and controlled electric potential environments. Water is crucial in maintaining the native state of biomolecules, while the electric methods are widely used in …

A Study of The Effect of Membrane Targeting Antimicrobial Compounds on Ionic Transport Across Lipid Bilayer Membranes
… previously been shown to reduce the integrity of membranes, observed through the leakage of dye from bacterial membranes. The membrane-peptide interactions were compared using advanced lipid membrane biophysical techniques, including in-silico structural modelling, fluorescent membrane dipole …

Calcium and strontium ionic flux of lipid bilayers
Bilayer lipid membranes were formed from lecithin,. cerebroside, ceramide and tripalmitin. The electrical potential across the lecithin and cerebroside membranes were measured in the presence of Na+, Ca++ and Sr++, and from these membrane specific resistance, transference number and ionic flux were …

Structural effects of neutral lipids on the divalent cation-induced interactions of phosphatidylserine - containing bilayers
… (PS) are known to induce the adhesion of bilayer vesicles and form collapsed multibilayer structures in vitro, it was the aim of this study to examine how that interaction and the resultant structures might be modified by neutral lipid species. X-ray diffraction data from multilamellar …

Electrodynamic droplet actuation for lab on a chip system
… reliable method for the formation of artificial lipid bilayers within microfluidic platforms for measuring basic biophysical aspects of cell membranes, for biosensing and drug discovery applications. Formation of artificial bilayer lipid membranes (BLMs) was demonstrated at the interface of …

Simultaneous extraction of order parameters and orientational distribution fuctions from 31[superscript]P NMR spectra of magnetically partially oriented phospholipid bilayers
… profiles extracted from the NMR spectra of model membranes are a valuable source of information about their structure and molecular motions. To al1alyze powder spectra the de-Pake-ing (numerical deconvolution) ~echnique can be used, but it assumes a random (spherical) dist.ribution of orientations …

Consequences of Asymmetric Environment on the Mechanics of Lipid Bilayer
Lipid membranes are selective barriers that encapsulate cellular components and define the identity of organelles. A fundamental feature of membranes is an asymmetric distribution of lipids and proteins across them. While a basic level of asymmetry is maintained at all times, local and transient …
