Nanograss Boron Doped Diamond microelectrode arrays for recording and stimulating neuronal tissues
Résumé
We report on a new approach involving the use of Boron Doped Diamond (B-NCD) to fabricate Micro Electrode Arrays (MEAs). MEAs are common electrophysiology tools enabling to probe the neuronal activity distributed over large populations of neurons or from embryonic organs [1-3]. They allow recording neuronal network activities while delivering specific electrical stimulations. Specific MEAs can also be used to build neural prosthesis or implants in order to compensate for function losses due to lesions or degeneration of part of the Central Nervous System (CNS). Here the main advantage of diamond is its wide electrochemical window in aqueous electrolytes as well as its bio-inertness.
