Vesicles and vesicle gels - structure and dynamics of formation

摘要: Vesicles constitute an interesting morphology formed by self-aggregating amphiphilic molecules. They exhibit a rich structural variety and are of interest both from fundamental point view (for studying closed bilayer systems) practical (whenever one is interested in the encapsulation active molecules). In many circumstances vesicular structures have to be external forces, but great systems, where they form spontaneously. Here question arises whether this means that also thermodynamically stable structures, which at least some systems appears case. If such vesicles well defined size, it possible pack them densely thereby vesicle gels possess highly elastic properties even for relatively low volume fractions amphiphile. Conditions formation microstructure been studied detail case unilamellar vesicles. Another important topical issue dynamics formation/breakdown, as understanding transition process will open way deeper their stability allow controlling formed, processes. Significant progress study transformation processes has achieved, particular time-resolved scattering experiments.
