Atomic Force Microscope Studies of the Fusion of Floating Lipid Bilayers [PDF]
Biophysical Journal, 2007 This study investigated the fusion of apposing floating bilayers of egg L-alpha-phosphatidylcholine (egg PC) or 1,2-dimyristoyl-sn-glycero-3-phosphocholine. Atomic force microscope measurements of fusion forces under different compression rates were acquired to reveal the energy landscape of the fusion process under varied lipid composition and ...

Vesicle Fusion Observed by Content Transfer across a Tethered Lipid Bilayer [PDF]
Biophysical Journal, 2011 Synaptic transmission is achieved by exocytosis of small, synaptic vesicles containing neurotransmitters across the plasma membrane. Here, we use a DNA-tethered freestanding bilayer as a target architecture that allows observation of content transfer of individual vesicles across the tethered planar bilayer.

Cell-free protein expression systems in microdroplets: stabilization of interdroplet bilayers
, 2013 Cell-free protein expression with bacterial lysates has been demonstrated to produce soluble proteins in microdroplets. However, droplet assays with expressed membrane proteins require the presence of a lipid bilayer.

Spontaneous Expulsion of Giant Lipid Vesicles Induced by Laser Tweezers [PDF]
, 1996 Irradiation of a giant unilamellar lipid bilayer vesicle with a focused laser spot leads to a tense pressurized state which persists indefinitely after laser shutoff.

Untargeted Lipidomics of Vesicular Stomatitis Virus-Infected Cells and Viral Particles
Viruses, 2021 The viral lifecycle is critically dependent upon host lipids. Enveloped viral entry requires fusion between viral and cellular membranes. Once an infection has occurred, viruses may rely on host lipids for replication and egress.

A Simple Computer Model for Liquid Lipid Bilayers
, 2005 We present a simple coarse-grained bead-and-spring model for lipid bilayers. The system has been developed to reproduce the main (gel-liquid) transition of biological membranes on intermediate length scales of a couple of nanometres and is very efficient

Tuning ubiquinone position in biomimetic monolayer membranes [PDF]
, 2017 Artificial lipid bilayers have been extensively studied as models that mimic natural membranes (biomimetic membranes). Several attempts of biomimetic membranes inserting ubiquinone (UQ) have been performed to enlighten which the position of UQ in the ...

Lipid Bilayer Vesicle Fusion: Intermediates Captured by High-Speed Microfluorescence Spectroscopy [PDF]
Biophysical Journal, 2003 The fusion of lipid bilayers can be visualized under the fluorescence microscope, but the process is very fast and requires special techniques for its study. It is reported here that vesicle fusion is susceptible to analysis by microspectrofluorometry and that for the first time, the entire fusion process has been captured.
