| Outline of Final Research Achievements |
Towards realization of highly sensitive and parallel bio-assays, we first achieved integration of a digital microfluidic (DMF) device with a dense microchamber array. Using this integrated platform, we exchanged the contents of microreactors in the microchambers and demonstrated digital counting assays repeatedly. On the other hand, we proposed and demonstrated ratchet-based one-way transport of droplets in the DMF by fabricating channel walls that create asymmetric potential for the droplets. We then showed that, instead of asymmetric channel walls, a new design of micro-electrodes in the DMF device allows us to achieve the ratchet-based one-way transport of multiple droplets in more robust manner with more flexibility for realizing highly integrated digital microfluidic circuits.
