Journal ArticleDOI
Sphingomyelin/phosphatidylcholine/cholesterol phase diagram: boundaries and composition of lipid rafts
TL;DR: The diagrams here described are used to rationalize literature results, some of them apparently discrepant, and to discuss lipid rafts within the framework of liquid-ordered/liquid-disordered phase coexistence.
Journal ArticleDOI
Fluid–Fluid Membrane Microheterogeneity: A Fluorescence Resonance Energy Transfer Study
TL;DR: Large unilamellar vesicles of dimyristoylphosphatidylcholine/cholesterol mixtures were studied using fluorescence techniques, and FRET efficiency decreases as a consequence of phase separation.
Journal ArticleDOI
Nonequilibrium Phenomena in the Phase Separation of a Two-Component Lipid Bilayer
TL;DR: It is verified that the attainment of equilibrium is a very slow process, leading to large domains at infinite time, and the nonequilibrium structure stabilization is due essentially to temporarily rigidified C(12) chains in the interface between gel/fluid domains, which decrease the interfacial tension by acting as surfactants.
Journal ArticleDOI
Exclusion of a cholesterol analog from the cholesterol-rich phase in model membranes.
TL;DR: NBD-cholesterol is not a suitable cholesterol analog and its distribution behavior in phosphatidylcholine/cholesterol bilayers is in fact opposite to that of cholesterol.
Journal ArticleDOI
A study of thermally activated delayed fluorescence in C60
TL;DR: The existence of thermally activated delayed fluorescence in C is demonstrated by the study of the temperature 60... dependence 291-353 K of the fluorescence intensity of C degassed solutions as discussed by the authors.
