Electrochemical biosensor strip
First Claim
1. An electrochemical biosensor strip, comprising:
- a base;
an electrode system laid on the base and a portion of the electrode system exposed for an electrical connection adapted to a meter and a predetermined portion of the electrode system exposed for applying of a test reagent;
a cover cooperated with the base to form a cavity for drawing an analyte-containing fluid therein to react with the test reagent; and
a hydrophilic layer laid between the test reagent and the base and laid on the base corresponding to the cavity and excluding from the electrode system and laid on the electrode system about 50% to 0% of the electrode system corresponding to the test reagent.

Abstract
An electrochemical biosensor strip has a base, an electrode system, an optional spacer and a cover. The electrode system is laid on the base. The spacer is laid on the electrode system and exposes a portion of the electrode system for electrical connection with a meter and a different portion of the electrode system for application of a test reagent. The cover is covered on the spacer to form a cavity. Between the test reagent and the base, a hydrophilic layer is laid between them for increasing the binding effect of the test reagent on the base. The hydrophilic layer is laid on the area excluding from the electrode system and laid on the electrode system about 50% to 0% of the electrode system corresponding to the test reagent. The hydrophilic layer will not interfere with signal transmission of the electrode system so the test is more accurate.
