Abstract

An equilibrium phase belonging to the family of bilayer liposomes in ternary mixtures of dimyristoylphosphatidylcholine (DMPC), water, and geraniol (a biological alcohol derived from oil-soluble vitamins that acts as a cosurfactant) has been identified. Electron and optical microscopy reveal the phase, labeled L tv , to be composed of highly entangled tubular vesicles. In situ x-ray diffraction confirms that the tubule walls are multilamellar with the lipids in the chain-melted state. Macroscopic observations show that the L tv phase coexists with the well-known L 4 phase of spherical vesicles and a bulk L α phase. However, the defining characteristic of the L tv phase is the Weissenberg rod climbing effect under shear, which results from its polymer-like entangled microstructure.
