采用碳纤维作为基底材料,并利用光学显微镜进行观察,研究了磷脂分子在蒸馏水和无水乙醇体系中的聚集行为。实验结果表明,碳纤维在磷脂分子聚集过程中不可缺少,是磷脂分子聚集的必要条件。选用水和乙醇的混合溶液作为观察溶液时,其比例会影响磷脂分子的聚集。使用纯乙醇制备磷脂膜,并配合纯净蒸馏水进行观察,可以清楚地观察到磷脂分子聚集行为主要有3种:一是磷脂双分子层脱落聚集成聚集体;二是磷脂分子直接聚集形成聚集体;三是“前驱体”诱导聚集为聚集体。因而磷脂分子的聚集方式不惟一。
Carbon fiber was used as the substrate material and observed by optical microscopy.The aggregation behavior of phospholipid molecules in distilled water and anhydrous ethanol system was studied.The experimental results shown that carbon fiber was indispensable in the process of phospholipid molecular aggregation,and was a sufficient condition for the aggregation of phospholipid molecules.When the mixed solution of water and ethanol was used as the observation solution,the ratio of there affected the aggregation of phospholipid molecules.The preparation of phospholipid membranes with pure ethanol and observation with pure distilled water can clearly observe that there were three main types of phospholipid molecular aggregation behaviors:one was the separation of phospholipid bilayers into aggregates,and the other was that phospholipid molecules directly aggregated to form aggregates.It was the three ways in which the “precursor” induced aggregation into aggregates,and thus the manner of aggregation of phospholipid molecules was not unique.
