Polymer Supported Lipid Bilayer Membranes for the Integration of Transmembrane Proteins
… successful formation of supported multicomponent lipid bilayer membranes (sLBMs) from natural occurring lipids as well as synthetic lipids on a set of polymer cushions consisting of alternating maleic acid copolymers. Maleic acid copolymers provide a versatile platform to adjust the …

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 …

Influence of protein and lipid domains on the structure, fluidity and phase behavior of lipid bilayer membranes
The lipid bilayer forms the basic structure of the cell membrane, which is a heterogeneous matrix of proteins and lipids that provides a barrier between the interior of a cell and its outside environment. Protein and lipid domains in cell membranes can facilitate receptor localization, stabilize …

Lipid Bilayer Formation in Aqueous Solutions of Ionic Liquids
The formation of lipid bilayer membranes between droplets of ionic liquid is presented as a means of forming functional bimolecular networks for use in sensor applications. Ionic liquids are salts that have a number of useful properties, such as low melting points making them liquid at room …

Photoelectric Characterization of Bacteriorhodopsin Reconstituted in Lipid Bilayer Membrane
… purpose, a system was built to characterize the lipid bilayer membranes and to measure the photocurrent. The lipid bilayer membrane was characterized by its capacitance and resistance. A picoampere photocurrent was observed when Bacteriorhodopsin protein was present in the bilayer membrane and a …

Development of planar patch clamp with potentiometric calcium ion-selective electrode
<p>Ion channels are proteins in cell lipid bilayer membranes and act as pores which can adopt closed and open states, thus gating the flow of ions in and out of the cell. Patch clamp technology has been the proven standard for fundamental studies of ion channel activities. However, the technique …

Fluorescence imaging microscopy studies on single molecule diffusion and photophysical dynamics
… quantitative data analysis were determined. For lipid marker molecules diffusing in an artifcial lipid membrane, the optimum way of the single molecule trajectory analysis of the image sequences was explored. Furthermore, effects of all relevant artifacts (specifically low signal-to-noise ratio, …

An Open Loop Feed-Forward Control Scheme for Bioinspired Artificial Hair Cell Sensors
… designed to manipulate the DC potential across lipid bilayer membranes in artificial hair cell sensors. Inspired by the human cochlea's non-linear gain phenomenon, whereby the cochlea can increase or decrease the effective gain of the auditory system, this controller is the first step in …

Study of the enhancement effect of cyclopentadecanolide on protein permeation through lipid membranes
… a permeation enhancer in protein release through lipid bilayer membranes. We successfully designed a novel in-vitro membrane permeability model using liposomes and performed a series of transmembrane protein release experiments. These were carried out under a wide range of conditions in the …

Chemical and biological modification of porous silicon photonic crystals.
… An alternative biorecognition interface, hybrid lipid bilayer membranes, containing specific recognition elements for cholera toxin allows optical detection of affinity capture and concentration within the PSi. In addition, the suitability of chemically modified photonic crystals as reservoirs …

Efficient coarse-grained brownian dynamics simulations for dna and lipid bilayer membrane with hydrodynamic interactions
… data and previous simulation results. (2) Lipid bilayer membranes have been extensively studied by CGMD simulations. Numerical efficiencies have been reported in the cases of aggressive coarse-graining, where several lipids are coarse-grained into a particle of size 4 ~ 6 nm so that there …

Isolation and characterization of channel-forming proteins in the outer membrane of E. coli and Borrelia species
… studied for pore-forming activity in the black lipid bilayer assay. Histograms of conductance fluctuations were obtained from single-channel experiments with outer membrane preparations of B. hermsii, B. recurentis and B. duttonii. All strains had a different conductance fluctuation pattern with …

Solid-liquid interactions in microscale structures and devices
… macromolecular structures and self-assembly of lipid bilayer membranes. The principles governing this phenomenon have been applied to induce self-assembly of millimeter scale Si thin films into spherical and other 3D structures, which are then integrated into light-trapping photovoltaic (PV) …

Observing, Understanding, and Manipulating Biological Membranes
<p>The phospholipid bilayer is one of the hallmarks of eukaryotic life. This complicated two dimensionally fluid surface is composed of a double layer of lipids which have a region that is hydrophobic and a region that is hydrophilic. The lipid bilayer membranes of a cell act as a barrier that …
