报告摘要:
MMicelles and vesicles formed from amphiphiles in aqueous solution have properties which emerge from the assembly of the amphiphiles [1]. Compared to micelles with their hydrophobic interior, vesicles have an aqueous internal volume which is separated from the bulk aqueous solution by a semi-permeable membrane formed by the amphiphiles. Since this compartment property is one of the key features of all biological cells, vesicular structures may have played important roles as protocellular precursor systems of the first cells at the origin of life. In terms of applications, vesicles from amphiphilic lipids (liposomes) are investigated for pharmaceutical applications, e.g. as drug delivery systems. Less studied are vesicles as additives for promoting chemical reactions in aqueous media [2]. In this case, the soft and dynamic vesicle membrane provides a reaction environment which differs from the bulk aqueous solution and with this may alter reaction kinetics and reaction pathways.
