稳定的油包水乳液膜可以使用[二月桂基（二甲基）铵]溴化物（DDAB），阳离子表面活性剂制备。我们通过γ-CyD的仲羟基与DDAB形成离子对，制备了超小的环糊精（γ-CyD）纳米凝胶（γ-CyDngs）。荧光和NMR表征表明，与天然γ-CyD相比，γ-CyDng具有上级包合亲和力，有利于疏水化合物在水中的增溶。
Stable water-in-oil emulsion membranes can be prepared using [dilauryl(dimethyl)ammonium] bromide (DDAB), a cationic surfactant. We prepared ultrasmall cyclodextrin (γ-CyD) nanogels (γ-CyDngs) by forming ionic pairs between the secondary hydroxyl groups of γ-CyDs and DDAB. Fluorescence and NMR characterisation of the obtained γ-CyDngs revealed superior inclusion affinities compared with native γ-CyDs, beneficial for the solubilisation of hydrophobic compounds in water.
