Abstract :
The electrochemical characteristics of a novel all diamond fabricated boron-doped diamond microelectrode array (BDD-MEA) are critically appraised. The voltammetric response of simple electron transfer processes has been investigated and found to generate sigmoidal voltammetric curves. Furthermore, the device has been utilized for various analytical applications including, the direct detection of 4-nitrophenol over the concentration range 1.8–9.2 μM, manganese over the range 0.1–4.8 μM and the indirect determination of sulfide producing a limit of detection of 23 μM.
