Boron-doped diamond is a new electrode material for electrochemical applications. Due to the fabrication from methane and hydrogen gases boron-doped diamond electrodes are less expensive than platinum electrodes. Yet boron-doped diamond by far exceeds the electrochemical performance of metal-based electrodes. Especially the wide electrochemical potential window, the low background current and the low adsorption tendency make boron doped diamond electrodes particularly interesting for electrochemical trace analysis and neurochemistry. Fraunhofer researchers developed fabrication processes to reliably fabricate custom tailored boron-doped diamond electrodes. The material can be applied to a variety of substrates and shapes made from silicon, quartz, metals, and diamond.
