Abstract
Vesicle aggregation induced by different environmental factors, including the addition of divalent metal ions, decrease of pH, and increase of temperature--was investigated through turbidity measurement, fluorescence measurement, and transmission electron microscope observation in aqueous solutions of hydrolyzed styrene-maleic anhydride copolymer (HSMA) mixed with dodecyltriethylammonium bromide (C(12)Et(3)). The vesicle aggregation can be explained by the dehydration of the vesicle surface through cations addition or temperature increase based on an analysis of the interaction between vesicles. Moreover, the steric repulsion was introduced to the system and the control of vesicle aggregation was achieved.

Abstract
The effect of polyvalent metal ions Be2+, Mg2+, Ca2+, Sr2+, Ba2+, and La3+ on the phase transition behavior of hydrated bilayer of dipalmitoylphosphatidylcholine (DPPC) was investigated by differential scanning calorimetry (DSC) in relation to their ability to induce the aggregation of DPPC vesicles. The addition of the metal ions other than Be2+ provided DSC thermograms characteristic to a fully hydrated DPPC bilayer. By the addition of Be2+, the endothermic peak associated with the bilayer phase transition was shifted to that corresponding to partially dehydrated DPPC bilayer, which was reported by Kodama et al. (Biochem. Biophys. Acta 689, 567, 1982). This demonstrates that Be2+ causes dehydration of DPPC head group in hydrated bilayer and supports the speculation that the unusual property of Be2+ to induce the aggregation of PC vesicles is attributed to the destruction of repulsive hydration force due to the partial dehydration of vesicular surface.
