Abstract:
1. A system, comprising: a microfluidic device reader configured to receive a microfluidic device comprising an array of spaced-apart test zones, the test zones being disposed between an inner surface of a first substrate and an inner surface of a second substrate of the microfluidic device, at least one of the substrates being flexible, each test zone comprising a probe compound configured to participate in an assay for a target analyte, an optical detector includes a light source and is configured to sequentially detect light from at least one of the test zones when the at least one test zone is in a detection zone of the microfluidic device and the optical detector detects light when the distance between the inner surfaces at the corresponding location is reduced, wherein the detection zone has a width of detection perpendicular to major axis of channel, a translator configured to translate at least one of the microfluidic device and the detection zone of the optical detector relative to the other, a compressor configured to reduce a distance between the inner surfaces of the first and second substrates at locations corresponding to the detection zone of the optical device, a processor configured to receive a signal from the optical detector, the signal indicative of light detected from a test zone.
