Abstract
A system and method for detecting an analyte includes a waveguide configured to receive a narrow-band laser signal; and a sorbent material covering an analyte detection region of the waveguide, wherein the sorbent material is configured to sorb the analyte and bring the analyte to an evanescent field of the waveguide, and wherein Raman scattering is produced by an interaction of the evanescent field and the analyte sorbed in the sorbent material along the analyte detection region of the waveguide, and the waveguide is further configured to collect the Raman scattering along the analyte detection region of the waveguide, wherein the collected Raman scattering indicates a type of the analyte.
