Abstract

A cycle of positive and negative voltage pulses applied to an electrode sensor removes passivation of an electrode surface. The conditioned sensors have improved sensitivity to concentrations for analytes of interest. The electrode surfaces can also be passivated on purpose to reduce sensitivity. The voltages applied are varied according to the solution present.
