Abstract
A system for performing nanostructure-enhanced Raman spectroscopy (NERS) includes a radiation source, a radiation detector configured to detect Raman scattered radiation scattered by an analyte, and a container configured to provide a sealed enclosure. The NERS system further includes a turbulence generating device configured to generate random dynamic motion of a plurality of nanoparticles within the container. A method for performing NERS includes providing a container configured to provide a sealed enclosure, providing a plurality of nanoparticles each comprising a NERS-active material and an analyte within the container, causing random dynamic motion of the plurality of nanoparticles and the analyte, irradiating the plurality of nanoparticles and the analyte with radiation, and detecting Raman scattered radiation scattered by the analyte.
