Polyelectrolyte-induced peeling of charged multilamellar vesicles.
We study mixtures of charged surfactants, which alone in solution form uni- and multilamellar vesicles, and oppositely charged polyelectrolytes (PEs). The phase behavior is investigated at fixed surfactant concentration as a function of the PE-to-surfactant charge ratio, x. We find that, for x > 0, aggregates form. Light microscopy and X-ray scattering experiments show that the isoelectric poin...
متن کاملDirect measurement of interaction forces between charged multilamellar vesicles†.
Depletion-attraction induced adhesion of two giant (∼ 40 μm), charged multilamellar vesicles is studied using a new Cantilevered-Capillary Force Apparatus, developed in this laboratory. The specific goal of this work is to investigate the role of dynamics in the adhesion and de-adhesion processes when the vesicles come together or are pulled apart at a constant velocity. Hydrodynamic effects ar...
متن کاملDeformability of multilamellar vesicles.
Although a free unilamellar vesicle has zero or almost zero genuine surface tension, the multilamellar vesicle ("onion") exhibits a nonzero effective surface tension sigma(eff). The expression for sigma(eff) used in the literature is sigma(eff) approximately square root of kappaB/d(0), where B is the interaction modulus between the vesicle bilayers, d(0) the repeating distance between the bilay...
متن کاملReal-time observation of polyelectrolyte-induced binding of charged bilayers.
We present real-time observations by confocal microscopy of the dynamic behavior of multilamellar vesicles (MLVs), composed of charged synthetic lipids, when put in contact with oppositely charged polyelectrolyte (PE) molecules. We find that the MLVs exhibit astonishing morphological transitions, which result from the discrete and progressive binding of the charged bilayers induced by a high PE...
متن کاملMultilamellar Vesicles in a Commercial Surfactant System
The manufacture of concentrated detergent granules in the detergent industry can be achie®ed by the incorporation of surfactant pastes, such as linear alkylbenzene sulfonate ( ) ( paste LAS a lamellar liquid crystalline material surfactant concentration of ca. 78 ) wt. % . LAS paste was processed at 25 C and 60 C, in both the absence and presence ( ) of sodium disilicate Na O:2SiO additi®e, and...
