Application

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.

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.
