A novel redox-switchable wormlike micellar system was developed based on a mixture of selenium-containing zwitterionic surfactant and commercially available anionic surfactant sodium dodecyl sulfate, which reversibly and quickly responds to H2O2 and vitamin C, and shows circulatory gel/sol transition, reflecting changes in aggregate morphology from entangled worms to vesicles.

A “worm”-containing viscoelastic fluid based on single unsaturated C22-tailed amine oxide surfactant shows pH-controlled thermo-thickening behaviour.
