Abstract: A flu assay system including a sample module, a microfluidic nucleic acid amplification device, and an analyzer to facilitate fully automated nested recombinase polymerase amplification (RPA) on a sample delivered to the nucleic acid amplification device via the sample module. The assay includes providing a sample to a microfluidic device, and amplifying a target polynucleotide sequence in the sample. Amplifying the target polynucleotide sequence includes performing a first round of amplification on the sample to yield a first amplification product, and performing a second round of amplification on the first amplification product to yield a second amplification product. The second amplification product includes a smaller sequence completely contained within the first amplification product produced during the first round of amplification.

Abstract: The present invention relates to test devices for determining the presence of one or more analytes in a sample, methods for using such test devices and methods of manufacturing such test devices. The test devices comprise a substrate having disposed thereon, two or more conductive tracks, a reagent composition and a top layer covering a portion of the conductive tracks which forms, in combination with the substrate, a sample receiving chamber. At least one of the conductive tracks comprises a conductive polymer.
