A vehicle interlocking method based on detection of analytes in exhaled breath

A method of interlocking vehicles is disclosed based on exhaled breath directed onto a SERS sensor. When a drug substance is detected in exhaled breath of a subject, said vehicle is locked from use for at least a pre-determined time or a repeated exhaled breath test where no drugs are detected.

Summary:A method of interlocking vehicles is disclosed based on exhaled breath directed onto a SERS sensor. When a drug substance is detected in exhaled breath of a subject, said vehicle is locked from use for at least a pre-determined time or a repeated exhaled breath test where no drugs are detected. The collecting surface has a Surface Enhanced Raman Spectroscopy (SERS)-active layer (903) that comprises at least one SERS-active material. The collecting surface is arranged as an outer surface of a waveguide (901) for contact with exhaled breath, such that at least traces of said at least one drug substance in said exhaled breath can contact said SERS-active layer for read-out of a Raman shift spectrum that is detected in-situ for said detecting the presence or determining the quantitative amount of said at least one drug substance from said exhaled breath.
