Abstract
Section titled āAbstractāDiamond multi electrode arrays (MEAs) and ultraāmicro electrode array (uMEA) fabricated from boronādoped nanocrystalline (BNCD) thināfilms, show excellent performances when detecting cell activity in both amperometric and potentiometric applications. Furthermore they are suitable for delivering electrical stimulation to elicit bioelectric events. Results obtained with our previous 9āchannels uMEA for single cells at high spatial resolution, and 16āchannels MEA for multicellular samples, validated the signal quality of diamond MEAs in comparison with competing technologies. The latest progresses are reported in this paper were we describe a new generation of devices with enhanced performances: a 12āchannel uMEA for recordings from a single cell at high spatial resolution, and a 64āchannel MEA to accommodate larger multicellular samples. The technology is based on a 200 Ī¼m thin highātemperature glass with the same thermal expansion coefficient of silicon and a spināon seeding method. Preliminary experiments show excellent electrodes activity and a strongly improved transparency.
