Abstract

A sensor for detecting a drug substance (15) from exhaled breath of a subject in-situ. Its collecting surface has a Surface Enhanced Raman Spectroscopy (SERS)-active layer (14) of a SERS-active material. The collecting surface is arranged as an outer surface of a waveguide (12) for contact with exhaled breath, such that at least traces of said drug substance (15) in said exhaled breath can contact said SERS-active layer for read-out of a Raman shift spectrum.
