Current Rectification at Quartz Nanopipet Electrodes
Abstract
Ag/AgCl reference electrodes fabricated from pulled quartz tubes with orifice radii of 20 nm to 20 μm were characterized in KCl solutions of different concentrations by cyclic voltammetry. Linear current−voltage ( i − V ) dependence was observed with micropipet electrodes (with micrometer-sized tips) with the same concentration (0.01−1 M) of KCl inside and outside the pipet, but current rectification was found at nanopipet electrodes at KCl concentrations of ≤0.1 M (with nanometer-sized tips). This is attributed to formation of a diffuse electrical double layer within the tip orifice. The effects of electrode size, electrolyte concentration, and solution pH on the nonlinear i − V behavior of these electrodes were investigated. A model for the observed behavior shows the rectification to be caused by the permselectivity in the tip region and the geometric asymmetry of the tip orifice. This phenomenon may be important in studies of ion transport in charged channels and porous membranes.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
