   Abstract:
   Structural testing of digital microfluldic biochips targets the detection of physical defects, but it does not guarantee robust execution of target bloassays or the integrity of assay outcomes. Functional testing is needed to detect fluldic malfunctions. Such tests ensure whether or not, the elementary fluldic operations, such as droplet transportation, mixing, incubation, and splitting are reliably executed on the microfluldic array. Routing test and mixing/splitting test are two important steps in functional testing. We present two procedures for optimal bidirectional routing test and accelerated mixing/splitting test. Compared to previous methods, these procedures need significantly fewer droplet manipulation steps and reduced execution time. The proposed method of functional testing in an N × N microfluldic array requires only a constant number of mixing/splitting steps. Further, the test outcome is free from boundary errors related to droplet size that may arise during mixing/splitting test. © 2008 IEEE.
