Electric Field Mediated Emulsification in a Flow Focusing Microfluidic Device

Summary This invention describes a microfluidic electro-flow focusing device. The essence of the device is the application of an electric field at a flow focusing junction between two immiscible fluids. The electric field creates charged drops and large forces necessary for emulsification, while the flow-focusing stabilizes the droplet production even at high fields where a Taylor cone is present. One application of this technology is the generation of charged droplets with a narrow distribution in radius down to submicron sizes. Another application is for the making of controlled droplet coalescence by oppositely charged drops. It may also be used for droplet steering and controlled movement in channels.
