Dependence of zeta potential on polyelectrolyte moving through a solid-state nanopore
View through CrossRef
This paper presents a method for establishing the relationship between the zeta potential and the movement of polyelectrolyte through a solid-state nanopore by employing electrostatic-hydrodynamic theory. The influence of the salt concentration, the surface charge density, the zeta potential, and the relationship between them are discussed. For a selected polyelectrolyte driven by an electric field, the dependence of the zeta potential on the velocity of polyelectrolyte translocation is shown, which demonstrates that polyelectrolyte movement is mediated by the zeta potential and predicts that surface charge modification can become an effective means for managing and regulating polyelectrolyte translocation.
