摘要: 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.

摘要: A biosensor that utilizes a mediator, i.e., an isomer of phenanthroline quinone, 1,10-phenanthroline-5,6-dione, and a metal ion, such as manganese, with an enzyme dependent upon NAD(P)+, such as, for example, glucose dehydrogenase, for improving the hematocrit bias and oxygen bias of biosensors. The electrodes of the biosensors employing this mediator and a metal ion provide an accurate clinical response over a hematocrit range that ranges from about 20% to about 70% and over an oxygen tension range that ranges from about 1 kPa to about 20 kPa.

摘要: A device having a flow channel, wherein a layer of mesh is adhered to a surface forming a wall of a flow channel, but the layer of mesh is of such dimensions that the layer of mesh does not contact those portions of the device where electrochemical reactions occur and electrons flow. In one aspect, the invention provides a sensor, such as, for example, a biosensor, in the form of a strip, the sensor being suitable for electrochemical or optical measurement. The sensor comprises a base layer and a cover layer having a layer of mesh adhered thereto, and the base layer is separated from the cover layer by a spacer layer. The base layer, the cover layer having a layer of mesh adhered thereto, and the spacer layer define a flow channel into which a liquid sample is drawn therein and flows therethrough by means of wicking.

摘要: A biosensor in the form of a strip. In one embodiment, the biosensor strip comprises an electrode support, a first electrode, i.e., a working electrode, a second electrode, i.e., a counter electrode, and a third electrode, i.e., a reference electrode. Each of the electrodes is disposed on and supported by the electrode support. Each of the electrodes is spaced apart from the other two electrodes. The biosensor strip can include a covering layer, which defines an enclosed space over the electrodes. This enclosed space includes a zone where an analyte in the sample reacts with reagent(s) deposited at the working electrode. This zone is referred to as the reaction zone. The covering layer has an aperture for receiving a sample for introduction into the reaction zone. The biosensor strip can also include at least one layer of mesh interposed in the enclosed space between the covering layer and the electrodes in the reaction zone. This layer of mesh facilitates transporting of the sample to the electrodes in the reaction zone. In another embodiment, a biosensor strip can be constructed to provide a configuration that will allow the sample to be introduced to the reaction zone by action of capillary force. In this embodiment, the layer of mesh can be omitted. The invention also provides a method for determining the concentration of glucose in a sample of whole blood by using the biosensor of this invention.
