Vesicle can be prepared from aqueous mixtures of simple commercially available, single-tailed cationic and anionic surfactants. In this work, the I3/I1 value, Ie/Im value, and fluorescence lifetime of pyrene in different systems (see the preparation of samples) were determined. The essential affecting factors in the formation of vesicle can be deduced from the obtained results. It showed that large vesicle must form naturally before sanitation in 0.082 M octyltrimethylammonium bromide and sodium laurate pH=9.2 aqueous solution. While after sonication, only small vesicle exists, which can be proved further through electron microscope.
