Abstract

L'invention concerne un capteur enzymatique qui comprend une enzyme produisant un signal lorsqu'elle entre en contact avec un analyte ; un substrat ; et un agent de réticulation qui comprend une ou plusieurs fractions hydrophiles. L'enzyme est immobilisée dans le substrat au moyen de l'agent de réticulation hydrophile. On applique une membrane biocompatible qui comprend l'enzyme, le substrat et l'agent de réticulation hydrophile sur un capteur afin de former un capteur enzymatique. Le capteur enzymatique présente des fonctions de détection renforcées en ce qu'il améliore la diffusion des espèces réactives, ce qui accroît la sensibilité générale et la durée de vie du capteur. L'incorporation de fractions hydrophiles dans l'agent de réticulation permet d'optimiser l'hydratation du capteur et de former des canaux ou voies hydrophiles pour les espèces réactives, telles que H202 et l'analyte étudié. La membrane et le capteur enzymatique peuvent être utilisés dans un procédé de détection d'un analyte tel que le glucose.
