The dynamic side of the Hofmeister effect: a single-molecule nanopore study of specific complex formation.

Philip A Gurnev1, Daniel Harries, V Adrian Parsegian, Sergey M Bezrukov.   

Abstract

Beyond measurements of equilibria: An alpha-hemolysin nanopore is used as a single-molecule sensor to follow the effects of different salts on the complexation reaction of gamma-cyclodextrin and adamantane carboxylate (see picture). The kinetics underlying the dynamic equilibrium are studied to reveal qualitatively different dynamic actions of various cosolute salts.
