Analytical test strip with an electrode having electrochemically active and inert areas of a predetermined size and distribution
First Claim
1. A method for determining an analyte in a bodily fluid sample, the method comprising:
- applying a bodily fluid sample to an electrochemical-based analytical test strip having;
an electrically insulating base layer; and
a patterned conductor layer disposed over the electrically-insulating layer, the patterned conductor layer including at least one electrode;
wherein the at least one electrode has electrochemically inert areas, an electrically continuous electrochemically active area lattice, and non-conductive border regions separating the electrochemically inert areas and the electrically continuous electrochemically active area lattice, the electrochemically inert areas and electrically continuous electrochemically active area lattice being configured of a predetermined size and a predetermined distribution such that an electrochemical response of the electrode during use of the electrochemical-based analytical test strip is essentially equivalent to a predetermined electrochemical response of a screen-printed carbon electrode;
measuring an electrochemical response of the electrochemical-based analytical test strip; and
determining the analyte based on the measured electrochemical response.

Abstract
An electrochemical-based analytical test strip for the determination of an analyte (e.g., glucose) in a bodily fluid sample (such as a whole blood sample) includes an electrically insulating base layer and a patterned conductor layer (for example, a gold patterned conductor layer) disposed over the electrically-insulating layer. The patterned conductor layer includes at least one electrode with the electrode having electrochemically inert areas and an electrochemically active area(s). Moreover, the electrochemically inert areas and electrochemically active area(s) are of a predetermined size and a predetermined distribution such that electrochemical response of the electrode during use of the electrochemical-based analytical test strip is essentially equivalent to a predetermined electrochemical response.
