Lipid exchanges between dioctadecyldimethylammonium bromide monolayer and vesicles in the subphase
(2022-03-01)
Studies on the interaction of lipid monolayer with bilayer structures, such as vesicles, are relatively scarce in the literature. In order to ascertain whether these structures interact for cationic dioctadecyldimethylammonium ...
Vesicles with charged domains
(ELSEVIER SCIENCE BV, 2010)
This work summarizes results obtained on membranes composed of the ternary mixture dioleoylphosphatidylglycerol (DOPG), egg sphingomyelin (eSM) and cholesterol (Chol). The membrane phase state as a function of composition ...
Lipid domains in giant unilamellar vesicles and their correspondence with equilibrium thermodynamic phases: A quantitative fluorescence microscopy imaging approach
(2009)
We report a novel analytical procedure to measure the surface areas of coexisting lipid domains in giant unilamellar vesicles (GUVs) based on image processing of 3D fluorescence microscopy data. The procedure involves the ...
Phase transition in dioctadecyldimethylammonium bromide and chloride vesicles prepared by different methods
(Elsevier B.V., 2000-04-01)
The gel to liquid crystalline phase transition of the double-chained cationic dioctadecyldimethylammonium chloride and bromide (DODAX, X = Cl- or Br-) in aqueous vesicle dispersions prepared by non-sonication, sonication ...
Adhesion of like-charged lipid vesicles induced by rod-like counterions
(2018-01-01)
Adhesion of electrically charged lipid vesicles and subsequent formation of multi-vesicle aggregates can be induced by multivalent rod-like counterions. Motivated by recent experimental observations we calculate the ...
Giant phospholipid vesicles: Comparison among the whole lipid sample characteristics using different preparation methods - A two photon fluorescence microscopy study
(Elsevier Ireland, 2000-04)
Several methods for the preparation of giant unilamellar vesicles (GUVs) using synthetic phosphatidylcholine phospholipids were evaluated. We compared the physical characteristics - in terms of lamellarity and morphology ...
Light scattering on the structural characterization of DMPG vesicles along the bilayer anomalous phase transition
(ELSEVIER IRELAND LTDCLARE, 2012)
Highly charged vesicles of the saturated anionic lipid dimyristoyl phosphatidylglycerol (DMPG) in low ionic strength medium exhibit a very peculiar thermo-structural behavior. Along a wide gel-fluid transition region, DMPG ...
Spontaneous vesicles of sodium dihexadecylphosphate in HEPES buffer
(Academic Press Inc. Elsevier B.V., 2008-04-15)
The formation of spontaneous vesicles of dihexadecylphosphate (DHP) in a HEPES buffered solution at pH 7.4, the size, morphology and melting temperature, obtained by cryogenic transmission electron microscopy (cryo-TEM) ...
