Abstract
Solid-type SERS-active substrates (e.g., noble metallic nanostructured powders or noble metallic nanoparticle-coatings on beads, microbeads, particles, etc.) are contained within optically-transparent modules. The modules allow for the controlled introduction of analyte-bearing fluid(s) into SERS-active substrates. The modules also allow for the monitoring of SERS signals emanating from analyte(s) which have accumulated on the confined SERS-active substrates. These SERS signals may be monitored over time by direct readout of the SERS substrates through the optically transparent module for chemical analysis and chemical detection applications.
