Abstract

We have successfully produced emulsion droplets on a chip with size-control and on-demand droplet generation by using magnetically driven microtool (MMT). The MMT has parallel plate structure to be constrained in translational motion. With a lateral motion of MMT in microchannels, the hydrophobic fluid can be cut into different size of droplets and the hydrophilic fluid can inflow into the microchannels by the movement of MMT to obtain both of size-controlled and on-demand droplets actively. The size range of the produced droplet was improved three times as large as the previous system by employing novel hydraulic design of the chip, and also the leakage of the fluid was successfully prevented when it is chopped by using MMT.
