Chemical monitors based on surface-enhanced raman scattering

摘要

This paper presents an overview of the development of chemical monitors using the surface-enhanced raman scattering (SERS) technique. The SERS effect is based on recent experimental observations, which have indicated enhancement of the Raman scattering efficiency by factors up to 10$+8$/ when a compound is adsorbed on rough metallic surfaces having submicron protrusions. The focus of our research efforts is on the development of SERS-active sensors and instrumentation capable of field analysis and remote sensing.
