title: Hofmeister series and specific interactions of charged headgroups with aqueous ions.
abstract: In this paper, we propose a Hofmeister-like ordering of charged headgroups. To this purpose we review various literature data and complete them with some new experimental and computational results on interactions of ions with alkyl sulfates and carboxylates. We further combine the proposed headgroup ordering with the law of matching water affinities in order to obtain a general description and predictions of ion-headgroup interactions. Examples from colloidal chemistry and from biological systems are provided to illustrate the power of this approach.
