Abstract: A chromatography-surface enhanced luminescence (SEL) sensing system may include a chromatography subsystem to separate a sample into eluate fractions having different elution times, an SEL stage and an eluate fraction dispenser. The eluate fraction dispenser is to direct different eluate fractions onto distinct regions of the SEL stage based upon the different elution times.

Abstract: 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.
