An in situ SERS fiber-optic system for remote sensing was developed for exciting and collecting surface-enhanced Raman scattering (SERS) signals generated from a sensing probe having silver-coated microparticles deposited on a glass plate support. The geometry of the excitation and collection fibers is a head-on arrangement, with the fibers on opposite sides of the SERS substrate and with the angle between the fibers equal to 180{degree}. Remote measurements are performed with the SERS probe and the collection fibers immersed in the analyte solution. The analytical data relevant to the performance of the SERS fiber-optic system, such as spectral characteristics, limits of detection, signal response, and temporal behavior, are described.
