LOW VOLUME ELECTROCHEMICAL BIOSENSOR
First Claim
1. A biosensor having (a) an electrode support;
- (b) an arrangement of electrodes disposed on the electrode support, the arrangement of electrodes comprising at least a working electrode and at least a second electrode;
(c) a first conductive track leading from the working electrode to an electrical contact associated with the working electrode and a second conductive track leading from the second electrode to an electrical contact associated with the at least second electrode; and
(d) at least one reagent incorporated in at least one of the first conductive track leading from the working electrode to the electrical contact associated with the working electrode, or the electrical contact associated with the working electrode.

Abstract
A biosensor in which at least one reagent constitutes a portion of a working electrode, a conductive track leading from a working electrode to an electrical contact associated with a working electrode, or an electrical contact associated with a working electrode. For example, the biosensor can have a mediator or an enzyme or both incorporated into the working electrode itself. Other reagents can be dispensed on the electrode itself either directly or by impregnating a matrix, such as a mesh or a membrane, with the enzyme, and then placing the impregnated mesh or membrane over the electrode. Alternatively, the biosensor can have a mediator or an enzyme or both incorporated into the conductive track leading from the working electrode to an electrical contact associated with the working electrode. In another alternative, the biosensor can have a mediator or an enzyme or both incorporated into the electrical contact associated with the working electrode itself. Furthermore, the biosensor can have a mediator or an enzyme or both incorporated into at least two of the foregoing components of the biosensor.
