Abstract

Abstract : This work presents a promising method for enhancing the transparency of boron‐doped nanocrystalline diamond (BNCD) microelectrodes while preserving a good level of electrical and electrochemical performances. This method is based on the combination of selective growth of diamond on a quartz carrier and the adoption of stacked delta‐doping. The overall results show similar conductivity and at the same time better transparency in comparison with bulk doped diamond, making this technology particularly suited for applications based on simultaneous fluorescence and electrochemical detection of redox active molecules released from biological samples.
