Title
(EN) ELECTROCHEMICAL SENSOR AND METHOD FOR DETERMINING THE CONCENTRATION OF AN ANALYTE IN A SAMPLE
(FR) CAPTEUR ÉLECTROCHIMIQUE ET PROCÉDÉ POUR DÉTERMINER LA CONCENTRATION D’UN ANALYTE DANS UN ÉCHANTILLON
Abstract
(EN)
In vitro electrochemical sensor that provide accurate and repeatable analysis of a sample of biological fluid are provided. In some embodiments, the sensors have a measurement zone that has a volume less than the volume of the sample chamber. The measurement zone could have a volume of no more than about 0.2 µL.
(FR)
La présente invention concerne des capteurs électrochimiques in vitro qui fournissent une analyse précise et reproductible d’un échantillon de fluide biologique. Dans certains modes de réalisation, les capteurs comportent une zone de mesure qui présente un volume inférieur au volume de la chambre à échantillons. La zone de mesure peut avoir un volume n’excédant pas environ 0,2 µl.
