Abstract

The miniaturization of boron-doped diamond (BDD) electrodes is an important requirement for application to the study of electrochemical processes in living beings. In this work, we describe the fabrication and characterization of BDD electrodes with micrometer dimensions, with a particular emphasis on micro needle electrodes. As a result of the combination of the microelectrode size effect and the intrinsic properties of the diamond films, these electrodes showed not only a significantly lower background current than diamond macroelectrodes, but also an ability for use in analytical sensing in low conductive media. Accordingly, a wider range of experiments including in vivo measurements could be performed.
