Objective: Develop a new, cost-effective tool for in situ quantification and monitoring of perchlorate (and energetics such as RDX) in groundwater via fiberoptic surface-enhanced Raman scattering (SERS). (1) Fabricate SERS substrates using wet-chemical self-assembly and nanofabrication techniques; (2) construct a prototype fiberoptic SERS probe that is interfaced with a handheld Raman spectrometer; (3) develop and optimize methodologies by incorporating molecular recognition techniques with improved selectivity and sensitivity of SERS substrates; and (4) evaluate the performance and cost effectiveness of a new SERS probe for in situ field screening and monitoring at selected DoD sites.
