A method () for determining a concentration of an analyte in a fluid or fluid sample, comprises: providing () a SERS substrate comprising receptor molecules () capable of binding competitor molecules (); contacting () the SERS substrate () with a fluid (sample) comprising analyte () and such competitor molecules (); radiating () the SERS substrate () with a light source while measuring a SERS signal; and determining () a concentration of the analyte () based on the measured signal level. A corresponding device and system are also provided.

Method and device for detecting analytes

A method for measuring a concentration of a biogenic substance in a living body includes steps of: preparing an apparatus including a light source, a substrate which has periodic metal structures and generates surface enhanced Raman scattering light by being irradiated with light from the light source, and spectroscopic means which disperses and detects the light, wherein the periodic metal structure is arranged with first and second distances in first and second direction respectively, the first distance is set to generate surface plasmon by matching a phase of the light from the light source, and the second distance is smaller than the first distance and is set between 300 nm and 350 nm; irradiating the substrate with the light from the light source to generate the surface enhanced Raman scattering; detecting the scattering with the spectroscopic means; and calculating the concentration of the biogenic substance based on the scattering.
