Microfluidic based biochips as a composite microsystem offers an alternative platform for conventional laboratory procedures. In recent years a new generation of such lab on chip devices namely Digital Microfluidic Biochip is emerged as a suitable application for concurrent and scalable integration of multiple bioassay protocols. Dependability and accuracy are major issues for safety critical applications...
Digital micro fluidics based biochips is expected to play an important role towards point-of-care diagnostics, drug discovery, prevention of bio-terrorism and other biochemical applications. Design and testing of biochips always remained a challenging area of research. Structural testing of these bio-MEMS is ensured by smooth movements of test droplets within the micro fluidic array. Partitioning...
The digital microfluidics technology has shown a great progress in the recent years. The testing of these types of biochips is crucial when used in widespread applications like clinical diagnostics, DNA sequencing, toxicity analysis etc. Thus these biochips must be tested adequately both offline after manufacturing and online during the biomedical assay. The MEDA based digital microfluidics offers...
Digital microfluidic biochips in recent years have been developed as a major alternative platform for conventional benchtop laboratory procedures. It offers better precision, scalability, higher sensitivity, lower cost due to smaller sample and reagent volumes. Testing of DMFBs is of major significance in terms of dependability and reliability issues for safety-critical applications. A series of complex...
Recent years have seen rapid progress in using digital microfluidics based biochips for biomedical assays. The testing and reliability of these biochips is crucial when they are used in point-of-care diagnostics applications. As the scalability and complexity of biomedical assays increases, there is a need for efficient testing methodologies to ensure reliability of these biochips. The conventional...
Digital micro fluidic technology is being increasingly used for implementing a lab-on-a-chip with many life-critical applications. Testing of these biochips is thus indispensable not only after manufacture, but also during in-field operation. To keep the product cost (including both design and test) low for disposable biochips, efficient on-line test techniques are desirable. All previous on-line...
This paper makes a case for design-for-testability (DFT) for microfluidic biochips, and presents a DFT method that incorporates a test plan into the fluidic operations of a target bioassay protocol. By using the testability-aware bioassay protocol as an input to the biochip design tool, the proposed DFT method ensures a high level of testability, defined as the percentage of the electrodes or functional...
Structural testing of digital microfluidic biochips targets the detection of physical defects, but it does not guarantee robust execution of target bioassays or the integrity of assay outcomes. Functional testing is needed to detect fluidic malfunctions. Such tests ensure whether or not, the elementary fluidic operations, such as droplet transportation, mixing, incubation, and splitting are reliably...
