Abstract :
Diamond ultramicroelectrode arrays (D-UMEAs) have been fabricated and evaluated experimentally for chemical sensing. D-UMEAs were found to demonstrate higher current density per unit active area than planar diamond macroelectrode and glassy carbon electrode. D-UMEAs could address new operating envelopes in electrochemical detection, and provide stable sensor electrodes for bio and extreme environments.
