Ionic Control of Droplet Motion
We demonstrate that an aqueous droplet containing calcium ions undergoes rhythmical oscillation in an organic phase containing a surfactant of phosphate group. The same oil/water interface exhibited the self-pulsing of the electrical potential. The patterns for the rhythmical oscillation and the self-pulsing were dramatically affected by the cation species.
