Surface tension and electroporation of lipid bilayers
Electroporation of lipid bilayers is widely used in DNA transfection, gene therapy, and targeted drug delivery and has potential applications in water desalination and filtration. A better, more thorough molecular understanding is needed, however, before such devices can be effectively used and …

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 …

Using Lipid Bilayers in an Artificial Axon System
… artificial axon system using droplet on hydrogel bilayers (DHBs) in conjunction with alamethicin channels was developed to show properties of action potential signal propagation that occur in myelinated nerve cells. The research demonstrates that the artificial axon system is capable of modifying …

Self-assembly of filopodia-like structures on supported lipid bilayers
… by applying frog egg extracts to supported lipid bilayers containing phosphatidylinositol(4,5)bisphosphate, PI(4,5)P 2. The FLSs recapitulate important characteristics of filopodia - they assemble parallel actin bundles from the lipid membrane and they form in the presence of capping …

Differential Interactions of Lipopolysaccharides with Lipid Bilayers: Applications for Pathogen Detection
… presentation of LPS by inserting the hydrophobic lipid A portion of the molecule into a lipid bilayer, leaving the O antigen exposed. This method is advantageous because it minimizes exposure of the highly conserved lipid A epitopes, and maximizes exposure of the serogroup specific O antigens. In …

Biostabilization of Lipid Bilayers: Dealing with Water Stress in Embryos of Artemia franciscana
… dissertation is to investigate stabilization of lipid bilayers during water stress by protectants found in embryos of Artemia franciscana. Two LEA proteins were used: AfrLEA2 and AfrLEA3m. AfrLEA3m was experimentally demonstrated to reside in the matrix. Two detergents were used to differentially …

Domain Redistribution in Lipid Bilayers in the Presence of the Antimicrobial Lipopeptide Fengycin
… microscopy was used to visualize and analyse lipid phase separation within supported lipid bilayers (SLBs) of various compositions. The initial research investigated the influence of protocol parameters on fluorescent probe distribution and lipid domain appearance within SLBs. The influence of …

Using Fluorescent Probes to Study the Location and Interaction of Disaccharides within Lipid Bilayers
… above the glycerol backbone of the phospholipids and is sensitive to any structural variations within the membrane. The data obtained with each respective probe indicates that the packing efficiency and polarity of the membrane is decreased in the presence of sucralose, but not in the …

pH-sensitive resist materials for combined photolithographic patterning of proteins and fluid lipid bilayers
… polymer was performed to pattern both lipid bilayers and proteins onto the same surface. The motivation behind this was to create a substrate mimicking an array of antigen- presenting cells. The substrate would consist of signaling ligand, biotin anti- CD3, bound to a lipid bilayer in a …

Molecular Dynamics Simulations for the Study of Biophysical Processes on Biological Membranes
Phospholipid bilayers constitute the primary structural element of biological membranes, and as such, they play a central role in biochemical and biophysical processes at the cellular level, including cell protection, intercellular interactions, trans-membrane transport, cell morphology, and …

Anions in hydrophobic environments: liquid-liquid extraction of sulfate and chloride, and membrane transport of chloride
The transport of an anion across a lipid bilayer or the extraction of an anion into organic solution requires the stabilization of a charged species in a hydrophobic environment. Due to the similar energetic barriers of both processes, liquid-liquid extraction can potentially be used as a model for …

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 …
