A novel, efficient, single fault detection technique of a digital microfluidic based biochip is presented in this paper. The proposed methodology is based on parallel scanning of the microfluidic biochip by using multiple droplets. The traversal of micro-array is carried out by scanning the intermediate rows, columns and the boundaries in parallel. This technique allows us to traverse all the cells as well as all edges for detecting fault in the Digital Microfluidic Biochip (DMFB). Correctness and Dependability are the important attribute for Digital Microfluidic Biochips that are used for safety-critical applications like point-of-care health assessment, massive parallel DNA analysis, automated drug discovery, airquality monitoring, and food-safety testing. Therefore, these devices must be tested after manufacturing and during bioassay operations. The experimental result suggests that the proposed approach is an efficient one and show significant improvement in fault detection.
