Ionic liquids and non-ionic surfactants: a new marriage for aqueous segregation

The aqueous nature of aqueous biphasic systems has boosted their use in downstream stages in biotechnological processes. Since aqueous solutions of non-ionic surfactants are widely used for different metabolites' purification, we have demonstrated for the first time their segregation capacity in the presence of ionic liquids.
