Lipid bilayer on a droplet: Formation of lipid bilayers on a droplet array
2012 IEEE 25th International Conference on Micro Electro Mechanical Systems (MEMS), 2012This paper describes a method for the formation of a lipid bilayer on a droplet-based chamber array. This method enables us to form small chambers sealed with lipid bilayers easily. The lipid membranes are stable and remain for at least 1 day. We successfully observed a transmembrane phenomenon via the lipid membrane on a droplet by fluorescent ...

Liposomes and lipid bilayers in biosensors
Advances in Colloid and Interface Science, 2017Biosensors for the rapid, specific, and sensitive detection of analytes play a vital role in healthcare, drug discovery, food safety, and environmental monitoring. Although a number of sensing concepts and devices have been developed, many longstanding challenges to obtain inexpensive, easy-to-use, and reliable sensor platforms remain largely unmet ...

Photoelectrospectrometry of bilayer lipid membranes
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1980These different bilayer lipid membrane systems were studied under visible and ultraviolet illumination. The first system consisted of a bilayer lipid membrane formed with a mixture of phospholipids and cholesterol, to one side of which purple membrane fragments from Halobacterium halobium were added.

The formation of lipid bilayers on surfaces
Colloids and Surfaces B: Biointerfaces, 2009The adsorption of biological molecules at solid-liquid interfaces is growing in importance due to its application to a very broad range of fields. Biomimetic systems like phospholipid mono- or bilayers are used to study such adsorption processes in great detail.

Adsorption of proteins on a lipid bilayer
European Biophysics Journal, 2010In our analysis of protein adsorption on a lipid bilayer, the protein surface is considered to contain one or a few charged spots, and the bilayer contains a significant amount of lipids with oppositely charged head groups. After adsorption, a folded protein is assumed to change its shape slightly due to the electrostatic attraction, so that one of the

Immobilization of proteins to lipid bilayers
Biosensors and Bioelectronics, 1996Phospholipid bilayers deposited on sensor surfaces are excellent substrates for immobilizing proteins via a molecular anchor. An integrated optics sensing device was used to accurately measure the binding kinetics of proteins thus anchored. By comparing the results with measurements using proteins from which the anchor had been enzymatically removed ...

NMR Spectroscopy of Lipid Bilayers
2010Knowledge of lipid structure and dynamics in a membranous environment is of first importance for deciphering cellular function. Sterols and sphingolipids are key molecules in maintaining membrane integrity and are the building blocks of membrane domains, such as "rafts".

Biocomputing with Nanostructures on Lipid Bilayers
Small, 2019AbstractBiocomputation is the algorithmic manipulation of biomolecules. Nanostructures, most notably DNA nanostructures and nanoparticles, become active substrates for biocomputation when modified with stimuli‐responsive, programmable biomolecular ligands.

The interaction of phenol with lipid bilayers
Chemistry and Physics of Lipids, 1984The depression of the phase-transition temperature of dimyristoyl- and dipalmitoylphosphatidylcholine vesicles induced by phenol has been investigated by fluorescence polarization. This effect is strongly pH and concentration dependent. Only the uncharged phenol molecule influences the fluidity of the bilayer so that the interaction of phenol with the ...

Proton permeation of lipid bilayers
Journal of Bioenergetics and Biomembranes, 1987Proton permeation of the lipid bilayer barrier has two unique features. First, permeability coefficients measured at neutral pH ranges are six to seven orders of magnitude greater than expected from knowledge of other monovalent cations. Second, proton conductance across planar lipid bilayers varies at most by a factor of 10 when pH is varied from near
