Surface-Enhanced Raman Detection of Nerve Agent Simulant (DMMP and DIMP) Vapor on Electrochemically Prepared Silver Oxide Substrates

摘要

Surface-enhanced Raman scattering (SERS) spectra of the chemical nerve agent simulants dimethyl methyl-phosphonate (DMMP) and diisopropyl methylphosphonate (DIMP) were obtained in the vapor phase. The spectra obtained demonstrate the possibility of detecting these nerve agent species in the vapor phase using electrochemi-cally roughened silver oxide substrates prepared from silver foil.
