Abstract
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 μL. 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.
