Properties of the mechanically grinded electrodes in these analytical applications were compared with some other carbon electrode types. We show that the electrode surface grinding with 15-mu M SiC particles resulted in a remarkable improvement of oxidation signals of purine bases with no addition of copper ions. Addition of the copper ions., causing a strong enhancement of the purine oxidation responses at fine-polished carbon electrodes, had only small effect on the purine signals at the g-PGEe. On the other hand, the g-PGEe appeared less suitable for the ex situ AdTS voltammetric measurements of nonhydrolyzed plasmid DNA, compared to freshly peeled basal plane pyrolytic graphite electrode.
