aggregates. This behavior enabled an easy approach for the preparation of vesicles by mixing micellar solutions of the gemini surfactants and SDS. Small vesicles with narrow size distribution were obtained. The high water solubility of the surfactants and the co-surfactant-induced micelle-vesicle transition suggest application potential for a delivery system focusing on an easy but effective encapsulation of

溴丙基糖苷烷基化,制备了一系列基于糖连接的双头基的新型双基尼型表面活性剂。这些表面活性剂专门以胶束组装,并显示出高
水溶性。头基团的强离子相互作用有利于与阴离子表面活性剂(如
SDS或
脂肪酸盐)的相互作用,从而导致层状聚集体。通过混合双子表面活性剂和
SDS的胶束溶液,此行为使制备囊泡的简便方法成为可能。获得具有窄尺寸分布的小囊泡。表面活性剂的高
水溶性和助表面活性剂诱导的胶束-囊泡转变表明了专注于简单但有效地封装
水溶性药物的递送系统的应用潜力。
