A polycrystalline Boron-Doped Diamond (BDD) square plate available in three sizes: 7 x 7 x 0.5 mm, 10 x 10 x 0.5 mm, and 15 x 15 x 0.5 mm. BDD is a semi-metallic material with high conductivity and fast electron transfer. Key advantages include: (i) outstanding chemical and dimensional stability, (ii) exceptionally low background current, (iii) an extremely wide potential window for water electrolysis, (iv) a broad electromagnetic transparency window from UV-Vis to far-infrared, (v) low magnetic susceptibility, and (vi) excellent biocompatibility (sp3 hybridized structure).

Application note

BDD is particularly important in electroanalysis for the development of sensors and biosensors. BDD electrodes allow detection of many electroactive molecules in aqueous media that would otherwise be masked by water decomposition reactions at higher potentials. The surface can be further (photo)functionalized or decorated with metal nanoparticles (e.g. Au). BDD is also used for electrochemical energy storage, electrocatalysis, and electrosynthesis.

Please note: The two larger surfaces have non-equal properties due to post-processing. One surface is polished while the other is laser-cut then polished, which affects boron doping level and conductivity. Chemical etching is recommended before use.
