Influences of Hofmeister Effects on Surface pH and Binding of Peptides to Membranes

Bostrom, Mathias; Williams, David; Ninham, Barry

Description

An understanding of local surface pH and binding of peptides to membranes is of interest for a number of biological processes. Ionic dispersion forces that give rise to Hofmeister effects have not previously been taken into account by theories. It is demonstrated that pH-changes near surfaces (e.g. membrane and mica) and binding of peptides to membranes depend on the specific ionic species. Near mica surfaces, the effect can be especially large: some anions, for example, Br-, experience large...[Show more]
