Abstract

A sensor which has at least first and second electrodes and a volume therebetween for receiving a liquid sample, includes an agent that lyses cells, wherein the lysing agent is in or on the surface of the first electrode.

Claims

1. A sensor comprising at least first and second electrodes and a volume therebetween for receiving a liquid sample, and which includes an agent that lyses cells, wherein the lysing agent is in or on the surface of the first electrode.

2. The sensor according to claim 1, which also comprises an enzyme of which glucose is a substrate.

3. The sensor according to claim 1, which also comprises a spreading layer over at least the first electrode.

4. The sensor according to claim 1, wherein the lysing agent is comprised in a layer applied onto the first electrode.

5. The sensor according to claim 4, wherein an enzyme and/or a mediator are applied in one or more additional layers on the first electrode.

6. The sensor according to claim 1, wherein the lysing agent is comprised in the first electrode.

7. The sensor according to claim 6, wherein the first electrode comprises a carbon layer and, on top thereof, a carbon layer including the lysing agent.

8. sensor according to claim 1, wherein the lysing agent lyses red blood cells.
