Abstract
The invention is directed to devices and methods for performing rapid low-cost bioassays in self-contained disposable cartridges that provide efficient mixing of sample and reactants under a layer of liquid wax. Some embodiments additionally use gravity assisted distribution of sample and assay reagents in conjunction with an appliance containing all necessary valves, pneumatic sources, heat sources and detection stations.
