Abstract
The bio sensor platform is a rapid point-of-care (POC) device wherein detection of a target analyte from a liquid or solid substrate is performed in a single step using a fully integrated disposable test system that includes a test strip immunoassay. In operation, a user initiates the test by rupturing the bottom of a liquid-filled analyte capsule seated in a capsule sleeve. A small volume of liquid flows by capillary action from the capsule sleeve and through a restrictor port to a test strip chamber where contact with the absorptive sample pad of the test strip (among other things) moves liquid by capillary action upwardly through the test strip. The detection of the target analyte is resolved by the test strip reagents and the test results are obtained at a test result window where a portion of the test strip is exposed to the user.
