Abstract : The MEDINAS project aims at the fabrication of Micro-Electrode Arrays (MEA) that take advantage of a novel electrode material, namely synthetic conducting diamond, as the bio-interface material. Diamond enables the fabrication of electrodes with high biocompatibility, high electrochemical interfacing performances and long-term stability. The project aims at the development of diamond based MEAs for recording and stimulating of neuron networks for both in vitro applications (rigid substrate) as well as for in vivo retinal prostheses (flexible biocompatible substrate). The performances of this new technology were assessed as compared to standard metallic solutions. (C) 2011 Elsevier Masson SAS. All rights reserved.
