Good Biocompatibility

Boron-doped diamond (BDD) thin films, as one kind of electrode materials, are superior to conventional carbon-based materials including carbon paste, porous carbon, glassy carbon (GC), carbon nanotubes in terms of high stability, wide potential window, low background current, and good biocompatibility. Electrochemical biosensor based on BDD electrodes have attracted extensive interests due to the superior properties of BDD electrodes and the merits of biosensors, such as specificity, sensitivity, and fast response. Electrochemical reactions perform at the interface between electrolyte solutions and the electrodes surfaces, so the surface structures and properties of the BDD electrodes are important for electrochemical detection. In this paper, the recent advances of BDD electrodes with different surfaces including nanostructured surface and chemically modified surface, for the construction of various electrochemical biosensors, were described.

Voltammetry is the general term for all techniques in which the current is measured as a function of electrode potential. The voltammetric techniques can be applied for the quantitative analysis of inorganic and organic species and are best suited for substances which can be either oxidized or reduced on electrodes. These techniques are characterized by high sensitivity which results in the possibility of performing determinations at a low concentration level. In voltammetry, many different types of working electrodes are applied. One of the important groups are solid electrodes, among which carbon electrodes play an important role. They represent a good alternative to mercury electrodes, however, surface preparation before the usage is required. In this work anethole determination will be presented using three types of carbon electrodes: glassy carbon electrode, boron doped diamond electrode and carbon paste electrode. Optimization process will be also described.

Studying electrolysis processes in drinking water disinfection it was found that chlorate and perchlorate can be formed at high extent on several electrode materials. Formation potential differs by orders of magnitude comparing mixed oxide (MIO), Pt and boron doped diamond (BDD) anodes. Highest concentrations were found using the doped diamond electrodes. Extended studies showed that chlorate and perchlorate may be formed also in other processes of so-called Advanced Oxidation. Therefore, the authors propose both components as new inorganic assessment criterions in environmentally-oriented water treatment.

Electron exchange reaction rates were compared for boron-doped diamond (BDD), Pt, Au and RuO2 using [Ru(NH3)6]3+/2+ as a redox couple. The study was carried out by cyclic voltammetry; calculations were performed by Nicholson's procedure. The results show that the rate constants on BDD, Pt and Au are qualitatively similar, one order of magnitude higher than on RuO2. The outcome is explained in terms of the specific structure of the interface between oxides and electrolyte solutions.
