The Effect of Receptor Clustering on Vesicle−Vesicle Adhesion

Journal of the American Chemical Society, 2006
As part of our studies into how the localization of cell adhesion molecules into lipid rafts may affect cell adhesion, we developed Cu(1), a synthetic copper(iminodiacetate)-capped receptor able to phase separate from fluid phospholipid bilayers. The extent to which Cu(1) clustered into adhesive patches on the surface of vesicles could be controlled by

Theory for vesicle—vesicle and vesicle-plasmalemma interactions

Journal of Colloid and Interface Science, 1982
A 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 ...

Polymer Vesicles

Science, 2002
Vesicles are microscopic sacs that enclose a volume with a molecularly thin membrane. The membranes are generally self-directed assemblies of amphiphilic molecules with a dual hydrophilic-hydrophobic character. Biological amphiphiles form vesicles central to cell function and are principally lipids of molecular weight less than 1 kilodalton.

Photodestructible Vesicles

Langmuir, 2005
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.

Fluorinated Vesicles

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 ...

“Breathing” Vesicles

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.
