Boron Doped Diamond (BDD) electrodes exhibit excellent properties including awide potential window in aqueous media, high corrosion resistance, chemicalinertness, bio-compatibility and low background current. In order to increasetheir selectivity for analytical applications, several studies were carried outrecently on the possibility to deposit metal nanoparticles such as Pt or Ir onsuch BDD electrodes1,2,3,4. Indeed these nanoparticles bringinteresting electro-catalytic properties to the electrodes, thus offering thepossibility to address new analytes. Here an electrode array was developed,based on multiple BDD electrodes casted with various metal nanoparticles. Thesimultaneous detection of analytes by each electrode composing the array givespotentially a unique fingerprint to the analytes, thus increasing thespecificity and the selectivity of the sensor.
