Abstract:
1. A microelectrode comprising: a non-conducting layer formed from electrically non-conducting material presenting a planar surface; one or more projections of electrically conducting diamond extending at least partially through the non-conducting layer, the one or more projections presenting one or more planar areas of electrically conducting diamond; the one or more projections extend to the planar surface of the non-conducting layer presenting one or more planar areas of electrically conducting diamond co-planar with the planar surface of the electrically non-conducting material; and an electrical contact or contacts positioned directly on a back side of the one or more projections of electrically conducting diamond for connection to an external circuit, wherein the surface roughness of the one or more planar areas of the electrically conducting diamond is less than 15 nm.
