What to know about How sulfur oxidation states shape the behavior of sugar-based surfactant molecules

A research study investigated how changing the oxidation state of a sulfur atom in sugar-based amphiphilic molecules affects their behavior. The team found that the sulfur oxidation state alters the concentration at which aggregation occurs in water and changes the relationship between bulk aqueous aggregation and surface-tension-based interfacial activity. These findings suggest that sulfur oxidation state can be a new molecular design parameter for developing advanced, environmentally friendly materials.
