A surface enhanced infrared absorption stage may include a substrate, a static island extending from the substrate and a movable nano finger extending from the substrate. The static island may have a plasmonically active island cap and a dimension parallel to the substrate of at least one micrometer. The movable nano finger may be aligned with the dimension. The movable nano finger may have a plasmonically active finger cap closable to less than or equal to 5 nm of the island cap.
