mi·cro·e·lec·trode

(mī'krō-ē-lek'trōd),
An electrode of very fine caliber consisting usually of a fine wire or a glass tube of capillary diameter (10 mcm-1 mm) drawn to a fine point and filled with saline or a metal such as gallium or indium (while melted); used in physiologic experiments to stimulate or to record action currents of extracellular or intracellular origin.

microelectrode

(mī′krō-ĭ-lĕk′trōd′)
n.
A very small electrode, often used to study electrical characteristics of living cells and tissues.

microelectrode

An electrode made from a hairlike filament capable of penetrating a single cell (e.g., a neuron), which can deliver or sense minute electric currents.

Using FSCV, the negative holding potential allows for the adsorption and preconcentration of the positively charged dopamine and serotonin on the surface of the carbon fiber microelectrode. On the other hand, the negative holding repels the negatively charged ascorbic acid, which is diffusion controlled onto the surface of the electrode rather than adsorption controlled.
An alternative to the micropore approach, significantly less prone to the clogging risk, is the use of microelectrodes for the confinement of the electric field.
