Research Activities

A major area of our research is concerned with the self-assemblies (such as micelles, vesicles, physical gels etc.) of synthetic biocompatible surfactants and polymers in both aqueous and non-aqueous media. With a wide range of techniques (fluorescence, UV-visible spectroscopy, rheology, static and dynamic light scattering, light and electron microscopy, etc.), our group is interested in how these self-assembled micro/nano-structures could be used as stimuli-responsive drug/gene delivery system. Furthermore, the group is also interested in unraveling the interactions of these self-assemblies with macromolecules, in particular with transport proteins.

We have a program of research aimed at enantioseparations of drugs, pesticides, and small organic racemates by electrokinetic capillary chromatography (EKC). This technique uses self-assemblies of optically pure surfactant monomers as well as polymers as pseudo-stationary phases. Our group has been able to demonstrate improved selectivity and optical resolution of enantiomers by use of vesicles.
