title: Effect of calcium cation on lipid vesicle deposition on silicon dioxide surface under various thermal conditions.
abstract: Calcium cation (Ca(2+)) is a key element to the cell membrane functions. Its effects on liquid crystal vesicle deposition have already been learnt. In this study, it is found that Ca(2+) can also influence the gel vesicle deposition by controlling the vesicle rupture and fusion on SiO(2) at temperatures lower than the main transition temperature. Particular analyses were given to the vesicle-SiO(2) and inter-vesicle attractions that are originated from the Ca(2+) bridging effect. It is concluded that the aggregate condition of vesicles should be taken into consideration when dealing with vesicle deposition on a solid substrate.
