Patent

CA 2489535

Sensors and methods of making the same are disclosed. Sensors are microfabricated with multiple working electrodes (102) and a single, common counter electrode (104). The multiple working electrodes (102) can be fabricated in different geometrical configurations for advantageously analyzing multiple components simultaneously in the same microcell sensor (100). Furthermore, sensors according to certain embodiments of the invention include openings (108) to allow photometric analysis along with electroanalytical methods.

L'invention concerne des capteurs et leurs procédés de fabrication. Les capteurs sont microfabriqués à l'aide d'électrodes de travail multiples (102) et d'une seule contre-électrode commune (104). Les électrodes de travail multiples (102) peuvent être fabriquées selon différentes configurations géométriques pour permettre l'analyse avantageuse simultanée de composants multiples dans le même capteur à microcellules (100). Par ailleurs, les capteurs, dans certains modes de réalisation de l'invention, comportent des ouvertures (108) permettant une analyse photométrique ainsi que des méthodes électroanalytiques.
