Detection principle for a chemically modified electrode (CME) in which an analyte or reagent accumulated at a CME undergoes quantitative release (egress, stripping, expulsion, or microdosing) to the test solution, under electrochemical or chemical control.
Note: Different mechanisms are involved in controlled release from the CME depending on the nature of the analyte or reagent and the method of accumulation. In the case of accumulation by covalent bonding, the anchoring bond is cleaved (ruptured) electrochemically. In the case of ion-exchange accumulation, an ionic (redox or acid-base) analyte or reagent is released by neutralizing its charge or the charge of the ion-exchanging redox polymer film or conducting polymer film.
