    Oleoylethanolamide-based lyotropic liquid crystals as vehicles for delivery of amino acids in aqueous environment

    Mohammady, Sayed Z. ; Pouzot, Matthieu ; Mezzenga, Raffaele

    In: Biophysical Journal, 2009, vol. 96, no. 4, p. 1537-1546

    We have investigated the phase behavior of self-assembled lyotropic liquid crystals (LC) formed by ternary mixtures of oleoylethanolamide (OEA), water and arginine. OEA, a natural analog of the endogenous cannabinoid anandamide involved in the peripheral regulation of feeding, was selected as a main component due to its capacity to induce efficient decreases in food intake and gains in body mass....

    Structure of heat-induced β-lactoglobulin aggregates and their complexes with sodium-sodecyl sulfate

    Jung, Jin-Mi ; Savin, Gabriela ; Pouzot, Matthieu ; Schmitt, Christophe ; Mezzenga, Raffaele

    In: Biomacromolecules, 2008, vol. 9, no. 9, p. 2477–2486

    We report on the conformation of heat-induced bovine β-lactoglobulin (βlg) aggregates prepared at different pH conditions, and their complexes with model anionic surfactants such as sodium dodecyl sulfate (SDS). The investigation was carried out by combining a wide range of techniques such as ultra small angle light scattering, static and dynamic light scattering, small angle neutron...

    Structural and rheological investigation of Fd3m inverse micellar cubic phases

    Pouzot, Matthieu ; Mezzenga, Raffaele ; Leser, Martin E. ; Sagalowicz, Laurent ; Guillot, Samuel ; Glatter, Otto

    In: Langmuir, 2007, vol. 23, no. 19, p. 9618-9628

    In the present study we demonstrate that a bulk inverse micellar cubic phase of Fd3m structure can be obtained by adding a hydrophobic component, such as the food-grade limonene, to the binary system monolinolein/water in a well-defined composition. The Fd3m structure studied in this work had a very slow kinetics of formation, as a consequence of partitioning of water...
