Abstract:
1. A device comprising: a multi-layered substrate, the multi-layered substrate comprising a first layer and a coated metal layer, the coated metal layer comprising a heat-conducting metal layer and a plastic polymer coating on the heat-conducting metal layer for preventing corrosion of the heat-conducting metal layer, wherein the first layer and the coated metal layer are sealably bonded together; a sample-distribution network defined by the multi-layered substrate and comprising (i) a sample inlet, (ii) two or more detection chambers, each of the two or more detection chambers being defined by the coated metal layer such that the plastic polymer coating separates the heat-conducting metal layer from the detection chamber, (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.
