Electro-tactic ionic liquid droplets

Conference Paper


Abstract


  • Herein we report the behavior of electro-guided, self-propelled droplets, which are composed solely of an ionic liquid (IL), namely trihexyl(tetradecyl)phosphonium chloride ([P6,6,6,14][Cl]). These selfpropelled droplets travel along an aqueous-air boundary, and are guided to specific destinations within the fluidic network through the use of electrochemically generated dynamic Cl- gradients. The speed, trajectory and direction of movement can be controlled by switching the voltage (ON or OFF in the range 5-9 V) and polarity of embedded electrodes that are in contact with a low ionic strength electrolyte solution (10-3 M NaCl) present in the channels.
