1.1 The Physics of Droplet Generation

An emulsion is a mixture of two or more unmixable (immiscible) liquids in the form of a droplet or a particle with the terms being used interchangeably. Single emulsions are created by dispersing one liquid (dispersed phase) into another liquid (continuous phase). Examples of such emulsions are “water-in-oil emulsions”, where water and oil is the dispersed and continuous phase, respectively. The boundary between the dispersed and continuous phases is called the "interface." The emulsification process is often realized by driving the two liquid phases through separate micron- or nanoscale fluidic channels that meet at a certain point. Device geometry and appropriate tuning of flow rate settings in combination with material properties can promote interfacial instabilities for droplet generation. These devices are known as hydrodynamic flow focusing fluidic devices and hereafter are referred as emulsifiers.
