Device for measuring the glucose concentration of protein-containing of aqueous solutions in particular in interstitial tissue liquids, preferably in implantable micro - opto - electronic form

摘要

Assay for determining the glucose concentration in a body fluid sample comprises removing proteins from the sample by dialysis and introducing the sample into a measurement chamber for glucose determination by polarimetry and/or infrared spectrometry. An Independent claim is also included for apparatus for performing the assay, comprising: (i) a measurement chamber; (ii) a polarimetric detection system comprising a light source, a detector and devices for deflecting the measuring beam; (iii) a spectrometric detection system comprising a light source and a detector; and (iv) devices for amplifying the measurement signals.
