Sample preparation in digital microfluidics refers to the generation of droplets with target concentrations for onchip biochemical applications. In recent years, digital microfluidic biochips (DMFBs) have been adopted as a platform for sample preparation. However, there remain one major problem associated with sample preparation on a conventional DMFB. For conventional DMFBs, only a (1:1) mixing/splitting...
Recent advances in digital microfluidic biochips have led to a promising future for miniaturized laboratories, with the associated advantages of high sensitivity and reconfigurability. As one of the front-end operations on digital microfluidic biochips, sample preparation plays an important role in biochemical assays and applications. For fast and high-throughput biochemical applications, it is critical...
Recent advances of digital microfluidic biochips (DMFBs) have revolutionized the traditional laboratory procedures. By providing the droplet-based system, DMFB can perform real-time biological analysis and safety-critical biomedical applications. However, different droplets being transported and manipulated on the DMFB may introduce the contamination problem caused by liquid residue between different...
As the microfluidic technology advances, the design complexity of digital microfluidic biochips (DMFB) are expected to explode in the near future. One of the most critical challenges for DMFB design is the droplet routing problem, which schedules the movement of each droplet in a time-multiplexed manner. In this paper, we propose a fast routability- and performance-driven droplet router for DMFBs...
