In this paper, the influence of Ca2+ on the adsorption properties of 1,8-anilinonaphthalenesulfonate (ANS) and analogous probes to sonicated vesicles of phosphatidylcholine was studied by means of spectrofluorometry. The fluorescence of ANS added to the vesicle dispersion increases with the Ca2+ concentration in the inner media but remains constant when Ca2+ concentration is changed in the outside solution. However, the fluorescence decreases when large anions such as ClO4- are present in the external solution. Ca2+ inside large liposomes promotes a similar behaviour to that found in sonicated vesicles when they are osmotically contracted in hypertonic media. The results can be interpreted in terms of Ca2+ adsorption on the inner interface and a cooperative interaction between the monolayers.
