  • ANALYTE DETECTION PACKAGE HOUSING
    Publication number: 20180143135
    Abstract: In one example, an analyte detection package includes a substrate, surface-enhanced luminescence (SEL) structures extending from the substrate and a low wettability housing. The SEL structures have a first wettability for a given liquid. The low wettability housing extends from the substrate to form a chamber between the housing of the substrate about the SEL structures to receive an analyte containing solution. The housing has an inner surface adjacent the chamber, wherein the inner surface has a second wettability for the given liquid less than the first wettability.
