Vesicles of different morphologies were found to form in aqueous solutions of the surfactant sodium bis(2-ethylhexyl)sulfosuccinate, AOT, and in binary mixtures composed of AOT with poly(ethylene glycol) and poly(sodium 4-styrenesulfonate). Using electrical conductivity and fluorescence probing, two critical vesicle concentrations, cvc and cac, were determined. These critical aggregation concentrations correspond to different kinds of aggregates, which are easily observed by optical microscopy.
在表面活性剂双（2-乙基己基）磺基琥珀酸钠（AOT）的水溶液中，以及在由AOT与聚乙二醇和聚（4-苯乙烯磺酸钠）组成的二元混合物中，发现形成了不同形态的囊泡。通过电导率和荧光探针法，测定了两个临界囊泡浓度，即cvc和cac。这些临界聚集浓度对应于不同种类的聚集体，通过光学显微镜很容易观察到。
