Abstract
An integrated optical waveguide sensor system includes: an optical waveguide having a monolithic and roughened metallic layer on which a self-assembled monolayer is formed; an optical energy source for generating an optical excitation signal; and a spectrometer for detecting spectra of optical energy emitted from the optical waveguide. The waveguide facilitates multiple SERS responses resulting from interactions between the optical excitation signal and an analyte of interest that may be present on the surface of the self-assembled monolayer. Thus, the sensor system provides a sensor for detecting organic contaminants with a sensitivity of ppm and even ppb in some cases.
