  • Process for preparing an electrochemical test strip
    Patent number: 6723371
    Abstract: As embodied and broadly described herein, the invention provides an electrode test strip. The electrochemical electrode test strip comprises an insulating base plate, a electrode system on the base plate, a spacer which partially covers the electrode system and a channel trench with a constant width is formed thereof, a reactive film, and a cover on the spacer with an first opening thereof. Wherein the electrode system comprises at least a working electrode and a reference electrode, and the working electrode and the reference electrode is isolated. The reactive film contains at least on active species that can have a specific redox reaction with the analyte. The first opening exposes the channel trench, and two second openings are located at the two ends of the channel trench.
