Stable water-in-oil emulsion membranes can be prepared using [dilauryl(dimethyl)ammonium] bromide (DDAB), a cationic surfactant. We prepared ultrasmall cyclodextrin (gamma-CyD) nanogels (gamma-CyDngs) by forming ionic pairs between the secondary hydroxyl groups of gamma-CyDs and DDAB. Fluorescence and NMR characterisation of the obtained gamma-CyDngs revealed superior inclusion affinities compared with native gamma-CyDs, beneficial for the solubilisation of hydrophobic compounds in water.

Abstract
Stable water-in-oil emulsion membranes can be prepared using [dilauryl(dimethyl)ammonium] bromide (DDAB), a cationic surfactant. We prepared ultrasmall cyclodextrin (gamma-CyD) nanogels (gamma-CyDngs) by forming ionic pairs between the secondary hydroxyl groups of gamma-CyDs and DDAB. Fluorescence and NMR characterisation of the obtained gamma-CyDngs revealed superior inclusion affinities compared with native gamma-CyDs, beneficial for the solubilisation of hydrophobic compounds in water.File in questo prodotto:
