Patent ID: 7656525

Claim:
A fiber optic SERS sensor system, comprising: a Raman system and a SERS probe, wherein the Raman system includes a Raman probe interfaced with the SERS probe and an optical fiber system for transmitting a light to the Raman probe from a light source and transmitting a signal light from the Raman probe to a Raman detection system; and the SERS probe includes a SERS probe structure and a SERS substrate, wherein the SERS probe structure includes a SERS substrate opening, a sample opening, a Raman probe opening, and a window, wherein the SERS substrate is disposed within the SERS substrate opening, wherein the Raman probe is disposed in the Raman probe opening that is along the longitudinal axis of the SERS probe structure so that light transmitted through the Raman probe passes through the window and impacts with the SERS substrate.
