Abstract

We report a simple and robust method of liquid marble manipulation using dielectrophoresis (DEP). An electrode with high voltage bias picks and moves the liquid marble. Liquid marbles floating on a free liquid surface prevent evaporation and can serve as unique bioreactors. Moving a floating liquid marble allows for stirring and mixing of its content. We further used DEP to move liquid marbles across the liquid surface with high speeds. We also present an analytical model to accurately predict the motion of the liquid marble. The technique potentially allows for high-throughput and efficient handling of liquid marbles as a digital microfluidics platform.
