The longer the alkyl-chains are, the stronger the surface activity of cosurfactant is. It's liable to form mixed film at interface with surfactant. Alcohol with short chain has weak surface activity and"solubilize" in reverse micromulsion to adjust micropolarity of microemulsion, so alcohol not only to act as cosurfactant but also act as"cosolute"in reverse microemulsion.

醇的碳链越长，表面活性越强，越易于进入界面与表面活性剂形成混合膜，短链醇的表面活性弱，主要溶解于反相微乳液中调节反相微乳液的微极性；因而醇在反相微乳液中的作用不仅是助表面活性剂也是助&溶剂&。

In this study, nonionic surfactant sorbitan trioleate (Span 85) was modified with Cibacron Blue F-3GA to become an affinity surfactant (CB-Span 85) and to form affinity-based reversed micelles while dissolved in hexane. Since the CB molecule possesses a specific conformation that mimics nicotinamide adenine dinucleotide, it can bind strongly and specifically to a wide range of nucleotide-dependent enzymes such as dehydrogenases and kinases. Moreover, high protein transfer efficiency in the reverse micelles can be easily achieved by controlling the ionic strength of the aqueous phase.

本实验使用非离子型界面活性剂Span 85与蓝色染料分子Cibacron Blue F-3GA结合，形成具有亲和性的界面活性剂 CB-Span 85，由於CB染料分子具有与NAD+相似的结构，可与含核苷酸部位的蛋白质具有亲和力，将CB-Span 85溶於有机溶剂形成反微胞相，可有效的提高反微胞的选择率，可以只控制离子强度来调节蛋白质进出反微胞的效率。
