Raman spectroscopy probe and raman spectroscopy apparatus

A Raman spectroscopy probe, comprising

• an elongate body having a proximal end and a distal end,
• an optical transmission line within the elongate body for guiding light for inducing Raman scattering in a tissue between the proximal end and the distal end in a distal direction and for guiding Raman scattered light between the distal end and the proximal end in a proximal direction, and
• a magnification layer arranged at or on the distal end, the magnification layer having an exposed surface for contacting the tissue,
• wherein the magnification layer is positioned such that the light for inducing Raman scattering impinges on the magnification layer,
• wherein the magnification layer is for inducing surface-enhanced Raman scattering (SERS) at the exposed surface,
• wherein the optical transmission line includes at least one illumination fibre for guiding light from the proximal end to the distal end and at least one collection fibre for guiding light from the distal end of the proximal end, and
• wherein the magnification layer is positioned in optical communication with the at least one illumination fibre and is positioned not in optical communication with the at least one collection fibre.
