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 1.8-9.2muM, manganese over the range 0.1-4.8muM and the indirect determination of sulfide producing a limit of detection of 23muM.

摘要

对一种新型全金刚石制造的硼掺杂金刚石微电极阵列（BDD-MEA）的电化学特性进行了严格评估。研究了简单电子转移过程的伏安响应，发现会产生S形伏安曲线。此外，该装置已用于各种分析应用，包括直接检测浓度范围为1.8 - 9.2μM的4-硝基苯酚、浓度范围为0.1 - 4.8μM的锰以及间接测定硫化物，检测限为23μM。
