摘要：

Modified graphite electrodes were prepared with materials containing carbonyl functional groups, including polypyrrole containing poly(methyl vinyl ketone). The effect of the modification on the electrochemical response of 2,6-diaminopurin-8-ol, a small, electrochemically fast biological molecule with primary amine groups which absorbs on active graphite, was evaluated. The results show that the chemical interactions between 2,6-diaminopurin-8-ol and the surface carbonyl functional groups do not by themselves contribute to the reactivity of the probe molecule.
