    l/Pa, wherein preparing the surface of the anode substrate comprises polishing the anode substrate, treating the anode substrate with a basic solution, treating the anode substrate with an acidic solution, or combinations thereof;

    forming a plurality of conductive nanostructures on the surface of the anode substrate via electrodeposition; and

    controlling at least one operating condition of the electrodeposition based on a target profile for the plurality of conductive nanostructures formed on the surface of the anode substrate, the target profile including the conductive nanostructures forming a plurality of freestanding structures.
