In this paper, we present a microfluidic device for droplet electrofusion with a continuously observation. The microfluidic device is composed of a hydrodynamic micro array system for trapping droplets and a pair of microelectrodes for applying electric field on the paired droplets. We fabricated the dynamic micro array device by standard soft lithography method and integrated microelectrode into the device by injecting low melting point alloy. We successfully trapped and fused a pair of droplets by applying direct current (DC) pulses. Furthermore, we confirmed the device allowed continuous observation for sequential fusion of droplets. We believe that this droplet electrofusion device will become a useful tool for droplet based chemical/biological reaction study.
