Abstract
An electrode structure is provided that includes an electrode base having topography located on a surface of the electrode base structure. A biological functionalization layer is located on one or more exposed surfaces of at least the topography of the electrode. A sacrificial layer is located on the biological functionalization layer and is present at least in the physical space located between the individual features of the topography of the electrode.
