Abstract

The invention is directed to a method and device for simultaneously testing a sample for the presence, absence, and/or amounts of one or more of a plurality of selected analytes. The invention includes, in one aspect, a device for detecting or quantitating a plurality of different analytes in a liquid sample. Each chamber may include an analyte-specific reagent effective to react with a selected analyte that may be present in the sample, and detection means for detecting the signal. Also disclosed are methods utilizing the device.

Claims

1. A device comprising:

a substrate;

a sample-distribution network defined by the substrate and comprising (i) a sample inlet, (ii) two or more detection chambers, (iii) at least one sample delivery channel in fluid communication with the sample inlet, and (iv) a plurality of dead-end fluid connections, each of the dead-end fluid connections providing a dead-end communication between a respective one of the two or more detection chambers and the at least one sample delivery channel; and

detection reagents in the detection chambers;

wherein the substrate comprises two or more layers, a high thermal conductivity metal surface, and a plastic polymer coating on the high thermal conductivity metal surface, and each of the two or more detection chambers is defined by the plastic polymer coating such that the plastic polymer coating separates the high thermal conductivity metal surface from the detection chamber.

2. The device of claim 1, wherein the high thermal conductivity metal surface comprises copper.

3. The device of claim 1, wherein the high thermal conductivity metal surface comprises aluminum.

4. The device of claim 1, further comprising an optically clear cover layer disposed over the sample distribution network.

5. The device of claim 1, wherein at least one of the two or more detection chambers comprises a dried detection reagent.

6. The device of claim 1, wherein the substrate defines at least two such sample-distribution networks.

7. The device of claim 1, further comprising means for modulating the temperature of the detection chambers, in the substrate.

8. The device of claim 1, wherein the two or more layers are laminated together.

9. A system comprising the device of claim 1 and an external temperature controller.
