New directions in structuring and electrochemical applications of boron-doped diamond thin films

摘要

Conductive boron-doped diamond electrodes have been shown to be highly suitable as electrochemical detectors in flow injection analysis and high performance liquid chromatographic analysis, achieving high sensitivity and stability for certain species that cannot be detected at other electrodes due to electrode deactivation or high electrochemical oxidation potential. The use of this electrode material for the detection of chlorophenols and theophylline is demonstrated. Apart from the electrochemistry of diamond, various methods have been developed to fabricate well-aligned nanocylindrical diamond films and periodic bulb-like structures, which may be useful for sensors and electronic devices such as field emission displays.
