A surface enhanced luminescence (SELS) sensor may include a substrate and nano fingers projecting from the substrate. Each of the nano fingers may include a polymer pillar having a sidewall and a top, a coating layer covering the sidewall and a metal cap supported by and in contact with the top of the pillar.

SELS nano finger sidewall coating layer

A surface enhanced Raman spectroscopy (SERS) sensor may include a nano structured surface and a nonstoichiometric oxide layer. The nano structured surfers may include a first peak, a second peak and a valley between the first peak and the second peak. The non-stoichiometric oxide layer may include a first portion on the first peak and a second portion on the second peak.

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.

A surfaced enhanced luminescence analyte interrogation stage shipping and storage package may include a sealed chamber, a liquid contained within the sealed chamber and nano pillars within the sealed chamber and submersed within the liquid. The nano pillars comprise polymer posts and metallic caps forming tips of the nano pillars.

A microfluidic chip may include a substrate, chamber supported by the substrate, a sacrificial material in the chamber, a spectroscopically active nano particle assembly anchored within the chamber by the sacrificial material and a fluid supply port connected to the chamber. Each spectroscopically active nano particle assembly may include a cluster of nanoparticles.
