摘要: A digital microfluidic biochip (DMFB) is an attractive platform for immunoassays, point-of-care clinical diagnostics, DNA sequencing, and other laboratory procedures in biochemistry. More recently, DMFBs based on a micro-electrode-dot-array (MEDA) architecture have been proposed, and droplet manipulations on MEDA biochips have also been experimentally demonstrated. In order to ensure robust fluidic operations and high confidence in the outcome of biochemical experiments, MEDA biochips must be adequately tested before they can be used for bioassay execution. This paper presents the first approach for testing of MEDA biochips that include both CMOS circuits and microfluidic components. We first present structural test techniques to evaluate the pass/fail status of each microcell (droplet actuation, droplet maintenance, and droplet sensing) and identify faulty microcells. In order to ensure correct operation of functional units, e.g., mixers and diluters, we also present functional test techniques to address fundamental MEDA operations, such as droplet dispensing, transportation, mixing, and splitting. We evaluate the proposed test methods using simulations as well as experiments for fabricated MEDA biochips.
