Charge inversion
of the surfaces of nanofluidic channels occurs
in systems with high-surface charge and/or highly charged ions and
is of particular interest because of applications in biological and
energy conversion systems. However, the details of such charge inversion
have not been clearly elucidated. Specifically, although we can experimentally
and theoretically show charge inversion, understanding at what conditions
charge inversion occurs, as well how much the charge-inverting ions
change the surface, are not known. Here, we show a novel experimental
approach for uniquely finding both the ΞΆ-potential and adsorption
time of charge inverting ions in aqueous nanofluidic systems.
