Stable vesicles are formed in a 1.4 wt % solution comprising a 1:3 mixture of the anionic photodestructible surfactant sodium 4-hexylphenylazosulfonate (C6PAS) and inert cationic cetyltrimethylamonium bromide (CTAB). UV irradiation drives an irreversible breakdown of the mixed C6PAS/CATB vesicles, owing to the selective degradation of C6PAS.

Journal of the American Chemical Society, 2009
A vesicle system is described that possesses a pH-induced "breathing" feature and consists of a three-layered wall structure. The "breathing" feature consists of a highly reversible vesicle volume change by a factor of ca. 7, accompanied by diffusion of species into and out of the vesicles with a relaxation time of ca. 1 min.

Theory for vesicle—vesicle and vesicle-plasmalemma interactions
Journal of Colloid and Interface Science, 1982A theory for predicting the approach velocity of a vesicle diffusing toward another vesicle or plasmalemma membrane is presented. This theory takes account of the shift between retarded and nonretarded van der Waals forces of attraction, the electrostatic forces of repulsion, and a spatially varying diffusion coefficient that considers the changing ...

Large vesicle contamination in small, unilamellar vesicles
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1980Small, unilamellar phospholipid vesicles have been prepared using a new, high-powdered cup sonifier that avoids contact of the sample with a titanium probe. These vesicles have been characterized by gel filtration chromatography both before and after fractionation by high-speed centrifugation.

Journal of Drug Targeting, 1994
Stable fluorinated vesicles--i.e. vesicles with a hydrophobic and lipophobic fluorinated film within their bilayer membranes--have been obtained from a variety of neutral, zwitterionic or anionic fluorinated amphiphiles, including single chain phosphocholine derivatives, double-chain phospholipids, glycolipids and glycophospholipids, as well as from ...

Creating Functional Vesicle Assemblies from Vesicles and Nanoparticles
Pharmaceutical Research, 2009Vesicles (liposomes) have been shown to be excellent vehicles for drug delivery, yet assemblies of vesicles (vesicle aggregates) have been used infrequently in this context. However vesicle assemblies have useful properties not available to individual vesicles; their size can cause localisation in specific tissues and they can incorporate more ...

The ability of certain lipids to self-assemble in water as bilayers is crucial for the properties of the outer membrane of biological cells and many of their internal structures as well (Golgi apparatus, endosomes, lysosomes, ...). Usually we call a vesicle such a bilayer membrane forming a closed shape with both an inner and an outer aqueous ...

Archives of Ophthalmology, 1981
Two male and four female patients had posterior corneal vesicles and scalloped lesions. Ages ranged from 7 to 24 years. Uncorrected visual acuities were 6/6 or better OU. All cases were unilateral. There was no other ocular abnormality. The lesions were at the level of Descemet's membrane and endothelium.

Vesicles and Vesicle Fusion: Coarse-Grained Simulations
2012Biological cells are highly dynamic, and continually move material around their own volume and between their interior and exterior. Much of this transport encapsulates the material inside phospholipid vesicles that shuttle to and from, fusing with, and budding from, other membranes.
