ABSTRACT:
The invention relates to a method and to a device for the non-invasive detection or determination, by Raman spectroscopy, of the concentration of substances in body fluids. The aim of the invention is to facilitate a non-invasive in vivo detection of substances in body fluids that allows for very accurate, reproducible results of analysis while requiring only little time for measuring which is acceptable for the patient. To this end, the inventive method and device for carrying out a Raman spectroscopy of a body fluid in a body tissue (1) records at least two Raman spectrums under different physical conditions and compares them with each other. The result of comparison allows detection of the substance one is looking for and measurement of the concentration of said substance.
