Boron-doped Diamond Ultramicroelectrodes
In recent years novel diamond electrodes have been developed, which exhibit electrochemical properties that are in many ways superior to more conventional electrode materials. Boron-doped diamond (BDD) is deposited on metal substrates using chemical vapour deposition (CVD) methodology, forming highly conductive films. When used as electrodes they show many attractive properties, such as a wide potential window, low background current and high resistance to fouling. In a very successful collaboration with Prof. John S. Foord at the University of Oxford (http://physche m.ox.ac.uk/~jsf/) we have development the methodology to reliably fabricate very sharp BDD UME tips of dimensions 1 - 50 microns. Although small diamond electrodes have previously been fabricated by other groups, our electrodes are the first of UME dimension that are suitable for use as SECM tips. The work has resulted in several publications and has recently been highlighted in the RSC 'Chemical Technology' magazine. http://www.rsc.org/Publishing/Chem Tech/ Volume/2007/10/ diamonds_ele ctron_microscopy.asp Work is now continuing on different insulation methods, modification of diamond surface for greater selectivity of analytes and application of the electrodes in biological media. This work was supported by the EPSRC (EP/D504805/1).
