CA 2466233

The invention is directed to conductive polymer compositions, catalytic ink compositions (e.g., for use in screen-printing), electrodes produced by deposition of an ink composition, methods of making, and methods of using thereof. An exemplary ink material comprises platinum black and/or platinum-on- carbon as the catalyst, graphite as a conducting material, a polymer binding material, and an organic solvent. The polymer binding material is typically or copolymer of hydrophilic and hydrophobic monomers. The conductive polymer compositions of the present invention can be used, for example, to make electrochemical sensors. Such sensors can be used in a variety of analyte monitoring devices to monitor analyte amount or concentrations in subjects, for example, glucose monitoring devices to monitor glucose levels in subjects with diabetes.

L'invention concerne des compositions polymériques conductrices, des compositions d'encre catalytiques (p. ex. utilisable en impression sérigraphique), des électrodes produites par dépôt d'une composition d'encre, des méthodes de fabrication, et des méthodes d'utilisation desdites compositions. Un matériau d'encre exemplaire comprend du noir de platine et/ou du platine sur carbone comme catalyseur, du graphite comme matériau conducteur, un matériau de liaison au polymère, et un solvant organique. Le matériau de liaison au polymère est généralement un copolymère de monomères hydrophiles ou hydrophobes. Les compositions polymériques conductrices de l'invention peuvent être utilisées, par exemple, pour fabriquer des capteurs électrochimiques. Ces capteurs peuvent être employés dans divers dispositifs de contrôle de substances à analyser pour contrôler la quantité ou la concentration desdites substances chez des sujets, comme par exemple, des dispositifs de contrôle de la glycémie chez des sujets diabétiques.
