Boron-doped diamond electrodes are becoming increasingly attractive, particularly in the electroanalytical and electrochemical waste water treatment fields. Recently, we have demonstrated applications of diamond electrodes for the detection of several chemical species whose detection is complicated with conventional electrodes such as glassy carbon or metal electrodes. Here, we summarize our recent electroanalytical work on diamond electrodes, emphasizing the dependence of surface termination (hydrogen or oxygen) on the selectivity of some specific biochemicals such as DNA and an oxidized form of glutathione (GSSG). Both voltammetric results and amperometric detection in flow systems are presented. The electrochemical modification of diamond with metal nanoclusters together with their electroanalytical applications are also discussed.
