Digital microfluidic (DMF) devices being able to control a group of submicro drops of liquid actuated by electrowetting are expected to be used to alternate biological or chemical experimental tools which have been currently equipped with bulky instruments, since for DMF devices there are certain advantages such as faster mixing and easier access to the digitalized drops. In this reason, DMF should become a next popular tool for lab-on-a-chip applications. While in most studies of DMF, the double-plate (closed) devices are conventionally adopted by many researchers, the single-plate (open) devices are a little studied, mainly because unexpectedly the digitalized drops of samples are not well actuated on a single plate. In this study, by applying an oil coating method to reduce the surface tension, we developed a novel open device that was successfully enabled to manipulate smoothly the various actuations of digital drops such as translational motion, merging and oscillation. This open DMF device should be usefully utilized, if properly integrated in the specific patterned electrodes for electrowetting control, for bio-, chemical- and medical liquid samples, likewise the electronic integrated chips. In the further work, we will perform to analyze various bio-samples on our newly developed planar DMFs.
