Biosensor
First Claim
1. A biosensor comprising:
- an insulating base plate;
an electrode system including at least a measuring electrode and a counter electrode formed on said base plate;
a cover member integrated into said base plate to form a sample solution supply pathway for supplying a sample solution to said electrode system between said cover member and said base plate;
a reaction reagent system including at least an electron mediator and an oxidoreductase; and
a carrier supporting at least the electron mediator or the oxidoreductase of said reaction reagent system,wherein said carrier is partially or wholly disposed outside said sample solution supply pathway.

Abstract
The present invention provides a biosensor which enables prompt quantification by facilitating introduction of a sample solution even when the amount of the sample solution is small and improving dissolution of reagents. The biosensor comprises an insulating base plate; an electrode system including at least a measuring electrode and a counter electrode formed on the base plate; a cover member integrated into the base plate to form a sample solution supply pathway for supplying a sample solution to the electrode system between the cover member and the base plate; a reaction reagent system including at least an electron mediator and an oxidoreductase; and a carrier supporting at least the electron mediator or the oxidoreductase of the reaction reagent system, wherein the carrier is partially or wholly disposed outside the sample solution supply pathway.
