Abstract: A surface enhanced luminescence analyte interrogation stage may include a substrate and an array of pillars projecting from the substrate. Each of the pillars may include a polymeric post formed from a first material and a cap on the polymeric post. The cap has a plasmonic surface and is formed from a second material different than the first. A sacrificial coating covers the cap of each of the pillars.
