Active Control of Surfactants-Base System

A second theme of research revolves around the design of light-sensitive and redox-active amphiphiles and development of principles for spatial and temporal control of surfactant-based interfacial and bulk solution properties. This research has led to light-sensitive surfactants that exhibit reversible micelle-to-vesicle transitions upon illumination, and redox-active surfactants that permit electrochemical control of micellization and Marangoni phenomena.

These surfactants have also been demonstrated to possess substantial utility for active control of microfluidic phenomena, including spatial and temporal control of wetting and self-assembly on the micrometer-scale. Active control of complexes formed between redox-surfactants and biomolecules has been demonstrated, leading to principles for spatial and temporal control of the delivery of DNA to cells.
