Dynamics of Giant Vesicles

Molecular Crystals and Liquid Crystals Science and Technology. Section A. Molecular Crystals and Liquid Crystals, 1997
Abstract The dynamics of vesicle shape transformations are governed by the competition between curvature energy, geometrical constraints and viscous dissipation in the surrounding liquid. After a discussion of the general principles, three examples illustrate these concepts, (i) Slow conformal diffusion of vesicles of higher genus arises from the ...

Transformation of oil droplets into giant vesicles

Chemical Communications, 2016
We propose a protocell model in which compartments are constructed via a new process involving the formation of robust vesicles using an autocatalytic, self-reproducing oil droplet system as a ‘scaffold’.

Asymmetrical labeling of giant phospholipid vesicles

Pflügers Archiv - European Journal of Physiology, 2000
The method for labeling of inner membrane leaflet in unilamellar giant POPC vesicles was developed and characterised. Symmetrically NBD-PC labeled vesicles were treated by sodium dithionite, which undergoes an irreversible chemical reaction with NBD-PC molecule making it non-fluorescent.

Membrane tensiometer for heavy giant vesicles

The European Physical Journal E, 2004
One key parameter of giant-vesicles adhesion is their membrane tension, sigma. A theoretically simple but delicate way to impose (and measure) it is to use micropipette manipulation techniques. But usually, the vesicles are free and their tension is unknown, until an adhesion patch grows.

Asymmetric Giant Lipid Vesicle Fabrication

2014
Synthetic lipid bilayers have long been used as models of cell membranes. The compositional asymmetry in the eukaryotic plasma membrane is a key chemical characteristic of this membrane that has traditionally been difficult to reproduce in synthetic systems.

Rheology of Giant Vesicles: A Micropipette Study

Physical Review Letters, 2004
We develop a micropipette rheometer to study the effect of oscillatory shear flow on the spontaneous fluctuations of phospholipid bilayers. Our results on giant vesicles show that oscillatory shear flow leads to a suppression of membrane fluctuations. They also imply that the Helfrich equation is modified in the presence of the flow.

Microdomain evolution on giant unilamellar vesicles

Biomechanics and Modeling in Mechanobiology, 2012
A chemo-mechanical model is used to capture the formation and evolution of microdomains on the deforming surface of giant unilamellar vesicles. The model is intended for the regime of vesicle dynamics characterized by a distinct difference in time scales between shape change and species transport.

The Giant Vesicle Book

2019
This practical manual gives the reader a toolbox for starting work with giant vesicles, including expert's tips on proper preparation methods, measurement, and characterization methods. The contents build from a simple model to use of vesicles as advanced membrane and cell system models. It also includes fundamentals for understanding vesicle structure,

Depth-Profiling with Giant Vesicle Membranes

Journal of the American Chemical Society, 2002
A phospholipid fluorescent-labeled in one of three locations was paired with a phospholipid labeled with a quencher in one of three locations within a host phospholipid bilayer. The various combinations of quenching efficiencies allowed the location of the fluorescent labels to be determined.

Electrofusion of giant unilamellar vesicles to cells

2015
We describe a method for electroporation-induced fusion of giant unilamellar vesicles (GUVs) with the plasma membrane of adherent cells. Using this method, the area of the cell membrane can be abruptly increased and various lipids can be introduced into the membrane.
