A surface enhanced luminescence system may include a laser and a controller to output control signals causing the laser to irradiate the pre-analyte exposed plasmonic surface while maintaining a profile of the pre-analyte exposed plasmonic surface.

Irradiation of plasmonic surfaces prior to analyte exposure

A luminescence-enhancement system can include a luminescence-enhancement sensor having a substrate and a group of nanofingers with individual nanofingers that can be flexible and include a support end attached to the substrate, a distal tip positioned distally with respect to the substrate, and a middle portion between the support end and the distal tip. A coating of a metal or metal alloy can be applied to the substrate and the distal tip that is conductively continuous. The middle portion can be devoid of the coating or the coating at the middle portion is conductively discontinuous. A liquid ejector can be present and can include a jetting nozzle to eject a liquid droplet having a volume of 2 pL to 10 &#x3bc;L. The group of nanofingers and the jetting nozzle can be positionable relative to one another for the droplet to be deposited on the group of nanofingers.

Luminescence-enhancement systems

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.

Surface enhanced luminescence analyte interrogation stage shipping and storage package

A surface enhanced luminescence analyte nano pillar stage may include a substrate, an array of closable pillars extending from the substrate and a fluid supply connected to the array of pillars. The fluid supply is to at least partially replenish fluid amongst the pillars of the array that has evaporated to maintain a level of the fluid amongst the pillars of the array below tops of the pillars.
