We prepared aqueous droplets containing Belousov-Zhabotinsky (BZ) solutions suspended on an oleic acid oil phase subject to DC electric field, and found that these BZ droplets undergo chemically driven translational motion towards the negative electrode under DC electric field. This electrotaxis phenomenon originates from the field-induced inhomogeneous distribution of reactants, in particular Br − ions, and consequently biased location of the leading centers towards the positive electrode. Chemical wave generated from the leading centre propagates passing the droplet centre of mass, and creates a gradient of interfacial tension when reaching the droplet-oil interface on the other side, resulting in a momentum exchange between the droplet and oil phases which drives the droplet move in the opposite direction of the electric field. A greater electric field strength renders stronger electrotaxis effect. Full Text Additional Declarations No competing interests reported.
