Abstract

Boron-doped diamond (BDD) is a well-established electrode material possessing unique properties [1], however, its performance can be significantly boosted by enlarging the effective surface area. For this reason, approaches focusing on fabrication of porous BDD (p- BDD) electrode materials have been emerging and such electrodes have attracted lots of research interest due to their enhanced detection ability [2-6], manifested by increased sensitivity, improved selectivity, and lower detection limits, favouring them in sensors development area. Besides sensing, another promising field in which p- BDD materials can be particularly beneficial, owing to their remarkable biocompatibility, is neuroscience. These materials have proved suitable (i) substrates for neuron cultivation [7], (ii) sensors for detection of electroactive neurotransmitters [2-6], and (iii) devices for stimulation or recording of electric signals [8]. Therefore, development of a p-BDD-based device, enabling cultivation of neurons and recording their neurochemical and electrical signals, can be envisioned.
