(last updated on 2022/12/30)Abstract:
Multiplexing several assays in time on the same digital microfluidic biochip is often needed in several biochemical applications. Contamination may lead to undesirable mixing of the residue left by one assay with the droplets of the subsequent assay. Hence, cleaning the droplet pathways of such a biochip by wash droplets between successive assays is required. Since a wash droplet may have a finite capability of residue removal, one has to design an efficient route planning for wash droplet(s) that minimizes the washing time and/or electrode actuation. In this paper, we formulate the problem in terms of graph Eulerization and Capacitated Chinese Postman Problem. We also propose efficient solutions and report some simulation results.
