Spreading kinetics of dimyristoylphosphatidylcholine liposomes at the air/water interface below and above the main phase-transition temperature

Influence of pH on colloidal properties and surface activity of polyglycerol fatty acid ester vesicles

“…Amongst the wide number of surfactants and surfactant aggregates, one particular type of structure, whose adsorption behavior to the air-water interface has been studied in great detail, are vesicles, especially vesicle dispersions of phospholipids. Owing to their physiological relevance, the spreading behavior of few phospholipids, also named as lung surfactants, has been subject to several studies [5][6][7][8][9]. While the exact mechanism of adsorption is still a matter for debate today [10][11][12][13], these studies have mostly shown that the adsorption behavior of surfactant from vesicle structures is strongly dependent on the physical state of the vesicle membrane [14][15][16].…”

Black Foam Films from Aqueous Solutions of a Mixture of Phospholipids and a Permeation Enhancer

“…As described earlier the aqueous solutions were obtained using the method of sonication, which leads to the formation of a suspension of small unilamellar vesicles (23). These vesicles upon reaching the solution/air surface transform from closed spheres into a surface monolayer, which is actually the adsorption layer (32). We could suppose that the molecules of the additional substance 4DO2O are incorporated into the vesicles during sonication, and they could change the kinetics of the process of vesicle transformation at the surface.…”

Comparative study of lipolysis by PLA2 of DOPC substrates organized as monolayers, bilayer vesicles and nanocapsules

“…Experimental results of (t) (Fig. 4) for the SUV can be converted in n * (t) by using a state equation of a monolayer of destructed vesicles similar to the state equation of a monomolecular layer, corresponding to Langmuir s model [28].…”
