Ion-Micelle Interactions and the Modeling of Reactivity in Micellar Solutions of Simple Zwitterionic Sulfobetaine Surfactants

Publication date: Available online 9 November 2019Source: Current Opinion in Colloid & Interface ScienceAuthor(s): Gustavo T.M. Silva, Frank H. QuinaAbstractAqueous micellar solutions of sulfobetaine surfactants provide a simple physical-chemical system for investigating the origin and consequences of the specific interactions of anions with a model zwitterionic interface. Studies of ground-state reaction kinetics in micellar solutions of these surfactants provide a window into some of the more intriguing aspects of both anion and cation interactions with a zwitterionic micelle surface. Recent molecular dynamics simulations paint a more physically reasonable picture of the zwitterionic micelle-water interface than that usually depicted in the literature and should contribute to our future understanding of the factors that contribute to specific anion binding.Graphical abstract
