Recent studies on liquid marble applications have shown the possibilities of using liquid marbles as biochemical or biological reactors. These potential applications of liquid marbles generate further interests in the investigation of materials and energy transport between liquid marbles to enable the control and manipulation of the biochemical and biological reactions inside them. In this study, the transport of electric charges between liquid marbles containing electrolyte solutions is demonstrated through a Daniell cell made with liquid marbles. Potential and current comparisons of the Daniell cells made using liquid marbles and solutions in beakers are made. Results show that charge transport between liquid marbles driven by electrochemical reactions is possible. Furthermore, the solution mixing conditions inside a liquid marble is also investigated experimentally and through modeling. The results offer a preliminary appraisal of the internal conditions of liquid marbles as a biological reactor. Crown Copyright (C) 2013 Published by Elsevier Ltd. All rights reserved.
