Abstract
Droplet transport technology doesn’t need channels to control fluids compared with traditional microchannel designs. This new concept gives several advantages: such as simple fabrication, easy droplet volume controlling, easy mixing, and low cost. 8×8 electrodes were applied for experiment chips in order to identify the EWOD phenomenon which makes the biomoleculer droplets moving. In order to observe the surface damage after droplet moving, proper AC power and low frequency were used for achieving optimal controlling parameters. The influence of important parameters for designing a better microfluidic transport device were discussed at the end.
