Single-lipid dynamics in phase-separated supported lipid bilayers [PDF]
Chemistry and Physics of Lipids, 2020 ABSTRACT Phase separation is a fundamental organizing mechanism on cellular membranes. Lipid phases have complex dependencies on the membrane composition, curvature, tension, and temperature. Single-molecule diffusion measures a key characteristic of membrane behavior and relates to the effective membrane viscosity ...

Hydrogen Bond Networks Near Supported Lipid Bilayers from Vibrational Sum Frequency Generation Experiments and Atomistic Simulations [PDF]
, 2018 We report vibrational sum frequency generation (SFG) spectra in which the C–H stretches of lipid alkyl tails in fully hydrogenated single- and dual-component supported lipid bilayers are detected along with the O–H stretching continuum above ...

Determining the Bending Rigidity of Free-Standing Planar Phospholipid Bilayers
Membranes, 2023 We describe a method to determine membrane bending rigidity from capacitance measurements on large area, free-standing, planar, biomembranes. The bending rigidity of lipid membranes is an important biological mechanical property that is commonly ...

Porous Materials to Support Bilayer Lipid Membranes for Ion Channel Biosensors
International Journal of Electrochemistry, 2011 To identify materials suitable as membrane supports for ion channel biosensors, six filter materials of varying hydrophobicity, tortuosity, and thickness were examined for their ability to support bilayer lipid membranes as determined by electrical ...

Fabrication of Supported Lipid Bilayer on Graphene Oxide
Journal of Physics: Conference Series, 2012 Planar lipid bilayers of dioleoylphosphatidylcholine was prepared on graphene oxide (GO), as a fundamental platform for biosensing in plasma membrane model using graphene. The GO flakes were prepared according to modified Hummer's method, and deposited on thermally oxidized SiO2/Si surfaces.

Electrophoretic Measurements of Lipid Charges in Supported Bilayers [PDF]
Analytical Chemistry, 2013 While electrophoresis in lipid bilayers has been performed since the 1970s, the technique has until now been unable to accurately measure the charge on lipids and proteins within the membrane based on drift velocity measurements. Part of the problem is caused by the use of the Einstein-Smoluchowski equation to estimate the electrophoretic mobility of ...

FEBS Letters, EarlyView.Plasma membranes contain dynamic nanoscale domains that organize lipids and receptors. Because viruses operate at similar scales, this architecture shapes early infection steps, including attachment, receptor engagement, and entry. Using influenza A virus and HIV‐1 as examples, we highlight how receptor nanoclusters, multivalent glycan interactions ...

Investigating Lipid-Protein Interactions Using Supported Lipid Bilayers
, 2016 Membrane proteins play vital roles in cell function and as such represent the targets of over 60% of pharmaceuticals on the market1. Lipid interactions with membrane proteins are a crucial but often overlooked effector of cell physiology.

Biophysical approaches for studying viral entry
FEBS Letters, EarlyView.Viruses infect all living organisms and have been responsible for major epidemics and pandemics. Their ongoing evolutionary battle with host defenses creates a constant need for improved tools to study viral behavior. Advancing methods to probe viral attachment, fusion, and genome release deepen our understanding of how infections begin and support the

Perturbation of Hydrogen Bonding Networks over Supported Lipid Bilayers by Poly (Allylamine Hydrochloride) [PDF]
, 2019 Water is vital to many biochemical processes and is necessary for driving many fundamental interactions of cell membranes with their external environments, yet it is difficult to probe the membrane/water interface directly and without the use of external
