Fluorescence temperature jump relaxations of dansylphosphatidylethanolamine in aqueous dispersions of dipalmitoylphosphatidylcholine during the gel to liquid-crystal transition.
The change of fluorescence of the probe dansylphosphatidylethanolamine embedded in multilamellar liposomes of dipalmitoylphosphatidylcholine was used to investigate the dynamics of the thermotropic gel to liquid-crystalline phase transition by use of the temperature-jump technique. The results are discussed and compared to published observations on the same system in which the phenomenon was reported by turbidity changes.
