Detecting Synthetic Opioids: Exploration of Surface-Enhanced Raman Spectroscopy and Development of Master Spectrum for Detection of Unknowns
Abstract
This effort, in support of the U.S. Department of Homeland Security, Science and Technology Directorate (Washington, DC), assessed the ability to augment current handheld Raman spectroscopic systems with surface-enhanced Raman spectroscopy substrates. The work was performed to understand pathways and analyze trace-level amounts of materials on contaminated surfaces. Additional work is reported on the construction of a unique single data element (library spectrum) that was developed with hundreds of synthetic opioid examples. The focus of this work was to assess whether the single spectrum could be used to detect the presence of an opioid even if the material was not in the systems database and had not been previously seen.
