Other Abstract

The introduction of electronic automation in the digital microfluidic (DMF) system has been highlighted it as a prospective platform for managing the intricacy of large-scale micro-reactors and underpinned a wide variety of on-chip biochemical applications such as immunoassays , DNA sample processing and cell-based assays. Yet, to further position DMF in high throughput applications such as cell sorting and drug screening, the velocity of the droplet transportation (vdroplet) must be improved, without compromising its reliability and controllability. The velocity of the droplet transportation depends on the actuation voltage and the size of the droplet. Empirically it barely reaches 2.5 mm/s at an droplet actuation voltage below 20 V .
