Abstract
The biosensor platform is a rapid point-of-care (POC) device wherein detection of a target substance is performed in a single step using a fully integrated disposable biosensor test system. In one embodiment, the system comprises a horizontally oriented multi-strip test cassette. A user initiates the test by depositing an analyte onto an immunochromatographic test strip sandwiched between a (top) cassette lid and a (bottom) slotted cassette tray. The test strip is held in place by at least one horizontally extending self-adjusting flex plate. The system is structured so that as the analyte flows through the test strip, the analyte reacts with a reagent in the test strip to indicate a presence or absence of the targeted substance as the test strip is held in place by the self-adjusting flex plate.
