Abstract
A microelectrode comprising a diamond layer formed from electrically non-conducting diamond and containing one or more pins or projections of electrically conducting diamond extending at least partially through the layer of non-conducting diamond and presenting areas of electrically conducting diamond.
Claims21
A microelectrode comprising:
- an electrically conducting diamond layer;
- a non-conducting diamond layer formed from electrically non-conducting diamond presenting a planar surface;
- one or more pins or projections of electrically conducting diamond extending at least partially through the non-conducting diamond layer, the pins or projections presenting planar areas of electrically conducting diamond;
- the pins or projections which extend to the planar surface of the non-conducting diamond layer, presenting one or more planar areas of electrically conducting diamond co-planar with the planar surface of the electrically non-conducting diamond;
- and
- an electrical contact positioned directly on a back side surface of the electrically conducting diamond layer for connection to an external circuit.
