Abstract :
In this paper, we demonstrate the method to generate an encapsulated droplet with precisely controlled water to oil volume ratio by merging individually created water and oil droplets through EWOD (electrowetting-on-dielectric) and DEP (dielectrophoresis) actuations, respectively. In addition, the 10cSt oil shell can be removed by mixing it with a volatile solvent. A bare droplet is obtained after the mixture is evaporated.
