Paper Abstract

The research presented in this paper improves potential for the application of surface-enhanced Raman scattering (SERS) in remote detection and analysis. Remote (stand-off) Raman sensing, with its ability to "fingerprint" analyte based on their unique vibrational spectra, offers great potential to address the challenging analytical problem of identifying unknown substances in low concentrations in the form of vaporous emissions or clouds. An inexpensive nebulizer/spray chamber was designed to study the mixing of aerosolized SERS (surface-enhanced Raman scattering) active nanostructures with a vapor phase analyte, the fluorophore Rhodamine 6G (R6G). Improved signal intensities (EF=200) are gained via SERS. Vapor phase mixing of the analyte and substrate is rapid (< 5 seconds).
