Abstract
A contact-type endoscope surface enhanced Raman scattering (SERS) probe includes a gradient-index (GRIN) lens, a transparent substrate adhered to the GRIN lens, and a rough metallic layer adhered to an opposite side of the transparent substrate from the GRIN lens. The GRIN lens focuses light from a Raman spectrometer onto the rough metallic layer, and the rough metallic layer is positioned at the distal end of the contact-type endoscope SERS probe.
