Electrode boron-doped diamond microelectrode

A simple cell using RVC has been described in Ref. [94]. A bare and gold-plated RVC electrode has been used in the study of microperoxidase [152], A bundle of cylindrical carbon fiber microelectrodes was used to monitor the catalytic reaction between ferrocyanide and ascorbic acid using the open-drcuit kinetic method [153]. While boron-doped diamond has shown great promise as a new electrode material, its transparency has not yet been exploited in UV-vis spectroelectrochemistry [154],... 

Other work by Kadara et al. [91] reported the fabrication of disposable and flexible screen-printed microelectrodes characterised by microscopy and cyclic voltammetry. The advantages presented by the fabricated electrodes included reduced expenditure and cleaning processes, as each of the microelecttodes is designed to be disposable the removal of the requirement of cleaning stages, but also pre-treatment between analyses, allows for a much more efficient and rapid analysis of samples the work also boasted exceptional detection limits with the screen-printed electrodes providing comparable detection limits to that obtained in the literature at insonated boron-doped diamond electrodes [91].

Microdisk array (MDA) electrodes of boron-doped diamond (BDD) were fabricated on structured silicon substrates. The BDD-MDA electrodes exhibited sigmoidal voltammetric curves, which show that they function as assemblies of single microelectrodes. The microelectrode behavior was also confirmed with biologically... 

Cooper et al. (1998) reported for the first time the fabrication and the use of boron-doped diamond (BDD) microelectrodes in non-aqueous electrolytes [21]. Considering the advantages of BDD mentioned above, the Fujishima group undertook the application of BDD microelectrodes, especially BDD microdisk [22], microfiber [23] and microdisk array [24] electrodes in aqueous solutions. 

Many of the chapters in this book have been devoted to various aspects of electroanalytical chemistry at diamond electrodes, for example, the preparation and characterization methods for BDD (Chapter 2), the question of the large potential working range (Chapter 3 for aqueous solution, and Chapter 6 for a wide variety of non-aqueous solutions), the influence of the boron doping levels on the kinetics for redox reactions (Chapters 4 and 5), the characterization and influence of the surface termination (Chapter 7 for hydrogen termination and Chapter 10 for oxygen termination), chemically modified surfaces in general (Chapter 9), metal-modified and ultrasmooth surfaces (Chapter 11), and the use of microelectrodes (Chapter 18) and nanostructured diamond electrode surfaces (Chapter 19).
