Optical sensor unit for infra red evanescence wave spectroscopy (IR-EWS) analysis of chemical and biological substances in an analyte, comprising a waveguide with a sensor surface to be put into contact with the analyte, wherein the sensor surface is provided with an affinity enhancing layer. There is further provided a method of producing an optical sensor unit.

Optical sensor unit for evanescence wave spectroscopy

A method and apparatus for measuring a vitamin K antagonizing anticoagulant present in a sample (), arranged to: irradiate () the sample () with light from a light source () for exciting the anticoagulant through its absorption of the light, the excitation of the sample () resulting in a fluorescent emission from the sample (); measure () the fluorescent emission from the sample (); determine () a fluorescence lifetime (T) of the fluorescent emission of the sample (); determine () an intensity (A) of the fluorescent emission at the fluorescence lifetime (T); and determine () a amount (c) of the anticoagulant, as a function of the intensity (A) of the fluorescent emission at the fluorescence lifetime (T).

Method and apparatus for detecting pharmaceuticals in a sample

A device, system, and methods are 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 that comprises at least one SERS-active material. The collecting surface is arranged as an outer surface of a waveguide 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.
