Figure 5. Schematic of the columns’ content on a molecular level. Left: only one band can be observed for solutions A and D. The micelles are not able to carry fluorescent dye molecules (however, Tyndall-effect showed, that micelles and dye were not entirely separated by the size exclusion column). Right: vesicular aggregates encase dye molecules, leading to two fluorescing bands.
