Studies of ionic current rectification using polyethyleneimines coated glass nanopipettes.
The modification of glass nanopipettes with polyethyleneimines (PEIs) has been successfully achieved by a relatively simple method, and the smallest tip opening is around 3 nm. Thus, in a much wider range of glass pipettes with radii from several nanometers to a few micrometers, the ion current rectification (ICR) phenomenon has been observed. The influences of different KCl concentrations, pH ...
متن کاملIon current rectification inversion in conic nanopores: nonequilibrium ion transport biased by ion selectivity and spatial asymmetry.
We show both theoretically and experimentally that the ion-selectivity of a conic nanopore, as defined by a normalized density of the surface charge, significantly affects ion current rectification across the pore. For weakly selective negatively charged pores, intra-pore ion transport controls the current and internal ion enrichment/depletion at positive/reverse biased voltage (current enters/...
متن کاملInfluence of electroosmotic flow on the ionic current rectification in a pH-regulated, conical nanopore.
The ionic current rectification (ICR) is studied theoretically by considering a pH-regulated, conical nanopore. In particular, the effect of electroosmotic flow (EOF), which was often neglected in previous studies, is investigated by solving a set of coupled Poisson, Nernst-Planck, and Navier-Stokes equations. The behaviors of ICR under various conditions are examined by varying solution pH, bu...
متن کاملControlling the ionic current rectification factor of a nanofluidic/microfluidic interface with symmetric nanocapillary interconnects.
The current rectification factor can be tailored by changing the degree of asymmetry between the fluid baths on opposite sides of a nanocapillary membrane (NCM). A symmetric device with symmetric fluid baths connected to opposite sides of the NCM did not rectify ionic current; while a NCM connected between fluid baths with a 32-fold difference in cross-sectional area produced a rectification fa...
متن کاملRectification of the ionic current through carbon nanotubes by electrostatic assembly of polyelectrolytes.
Rectification of the ionic current flowing through nanotubes embedded in a polymeric membrane is achieved by selective adsorption of polycations to the nanotubes' mouths. A one-dimensional model of ionic flux through a nanotube with charged entrance regions qualitatively describes current-voltage curves before and after polycation exposure; reversal potential measurements confirm that charge re...
