Abstract
Digital microfluidic (DMF) apparatuses, systems, devices and associated fluid manipulation and extraction devices, and methods of using them are presented. The devices may be useful for analysis of clinical, laboratory, chemical, or biological samples. A fluid application and extraction interface device may include a waste reservoir with a fluid trap and a transfer conduit extending through the waste reservoir so that fluid may pass from the transfer conduit into the waste reservoir and be trapped within the waste chamber. A transfer conduit may be configured to double back on itself and to hold a fluid sample. A DMF apparatus may be configured to hold and process large sample volumes.
