Electrowetting-on-dielectric (EWOD) chips have become the most promising technology to realize pin-constrained digital microfluidic biochips (PDMFBs). In the design flow of EWOD chips, reliability is a critical challenge as it directly affects execution of bioassays. The major factor to degrade chip reliability is the trapped charge problem, which is(More)
Electrowetting-on-dielectric (EWOD) chips have become the most popular actuators, particularly for droplet-based digital microfluidic biochip (DMFB) systems. In order to enable the electrical manipulations, wire routing is a key problem in designing EWOD chips. Unlike traditional very-large-scale-integration (VLSI) routing problems, in addition to(More)
Recently, digital microfluidic biochips (DMFBs) have revolutionized many biochemical laboratory procedures and received much attention due to many advantages such as high throughput, automatic control, and low cost. To meet the challenges of increasing design complexity, computer-aided-design (CAD) tools have been involved to build DMFBs efficiently.(More)

Synthesis of camphor derived chiral allenes and their hydroboration-oxidation reactions are described. Reaction of (1R)-(+)-camphor with alkynyllithium followed by the reduction of the resulted propargyl alcohol derivatives using AlH3 furnished chiral allenes 2a-g in excellent yields with high diastereoselectivity. Reduction of the propargyl alcohols with(More)
