Novel membranes comprising various polymers containing heterocyclic nitrogen groups are described. These membranes are usefully employed in electrochemical sensors, such as amperometric biosensors. More particularly, these membranes effectively regulate a flux of analyte to a measurement electrode in an electrochemical sensor, thereby improving the functioning of the electrochemical sensor over a significant range of analyte concentrations. Electrochemical sensors equipped with such membranes are also described.
L'invention concerne des nouvelles membranes qui comprennent divers polymères contenant des groupements d'azote hétérocyclique. Ces membranes sont utiles dans des capteurs électrochimiques, de type biocapteurs ampérométriques. Plus particulièrement, ces membranes régulent de manière efficace le flux d'une substance à analyser d'une électrode de mesure dans un capteur électrochimique, ce qui permet d'améliorer le fonctionnement de ce dernier sur une plage significative de concentrations de substances à analyser. L'invention concerne également des capteurs électrochimiques équipés desdites membranes.
