SURFACE-ENHANCED RAMAN SCATTERING FOR DRUG DETECTION IN EXHALED BREATH

A method is disclosed for detecting the presence or determining a quantitative amount of at least one drug substance from exhaled breath of a subject in-situ. A collecting surface has a Surface Enhanced Raman Spectroscopy (SERS)-active layer (14) that comprises at least one SERS-active material. The...

More Information
Summary:A method is disclosed for detecting the presence or determining a quantitative amount of at least one drug substance from exhaled breath of a subject in-situ. A collecting surface has a Surface Enhanced Raman Spectroscopy (SERS)-active layer (14) that comprises at least one 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 at least one drug substance (15) in said exhaled breath can contact said SERS-active layer for read-out of a Raman shift spectrum.
