Giant Lipid Vesicle Formation Using Vapor-Deposited Charged Porous Polymers.
Langmuir, 2018In this study, we prepare giant lipid vesicles using vapor-deposited charged microporous poly(methacrylic acid- co-ethylene glycol diacrylate) polymer membranes with different morphologies and thicknesses.

Asymmetric Giant Lipid Vesicle Fabrication
2014Synthetic 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.

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 ...

Current Opinion in Colloid & Interface Science, 2000
We have discussed the specific properties of giant vesicles and their use as model systems for fluid interfaces and biomembranes. Recent advances in giant vesicle research include systematic measurements of visco-elastic parameters as a function of membrane composition, experiments with water-soluble amphiphiles and active membranes, as well as the ...

Polymer Encapsulation within Giant Lipid Vesicles
Langmuir, 2007We report encapsulation of polymers and small molecules within individual giant lipid vesicles (GVs; 3-80 microm), as determined by confocal fluorescence microscopy. Polymer-bound or free dyes were encapsulated within GVs by including these molecules in the aqueous solution during vesicle formation via gentle hydration.

Membrane tensiometer for heavy giant vesicles
The European Physical Journal E, 2004One 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.

Aqueous Phase Separation in Giant Vesicles
Journal of the American Chemical Society, 2002We report the synthesis and initial characterization of approximately 10 mum diameter lipid vesicles that contain two distinct aqueous phases. The aqueous two-phase system is a dextran/poly(ethylene glycol) solution that exhibits temperature-dependent phase behavior. Vesicles were prepared above the phase transition temperature of the polymer solution.

Microdomain evolution on giant unilamellar vesicles
Biomechanics and Modeling in Mechanobiology, 2012A 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.

Asymmetrical labeling of giant phospholipid vesicles
Pflügers Archiv - European Journal of Physiology, 2000The 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.
