General description

Sodium dodecylbenzenesulfonate (SDBS) acts as a surfactant in the ionic self-assembly reaction of cyclophane BIMCP-1.

Sodium dodecylbenzenesulfonate is an ionic surfactant.


Sodium dodecylbenzenesulfonate has been used to stabilize dispersions of graphene nanoflakes (GNFs) during the preparation of the liquid phase of GNFs. It can also suspend single-walled carbon nanotubes as individuals in aqueous media and also give well-resolved spectral features.

Sodium dodecylbenzenesulfonate was used to fabricate amperometic biosensors for glucose.
