1. A structure comprising:
an electrode having topography located on a surface of an electrode base structure, wherein said topography is defined by individual articulated features;
a biological functionalization layer located on one or more surfaces of at least said topography of said electrode; and
a sacrificial layer located on said biological functionalization layer and present only in the physical space located between said individual articulated features of said topography of said electrode such that the biological functionalization layer located on a topmost surface of said topography of said electrode is physically exposed.
