The advance in the microfluidic technologies provides new means for microencapsulating active ingredients such as drugs, microbes, living cells, and functional materials in isolated spaces, and separating them from the outer environment.For instance, the core-shell double emulsions and the resulting microcapsules are thus attractive candidates for micro-reaction, targeted delivery and controlled release applications.To achieve these applications, the double emulsions or capsules have to be exposed to a range of specific stimulus to trigger the inner cores break, such as mechanical stress, changing in PH or temperature, changing in the external chemical environment, or UV exposure.In addition, the geometry of an emulsion or capsule plays an important role in these trigger process.Thus, more active stimuli and shaped emulsions and capsules should be designed to enable the trigger process easier and more accurate, and extend the range of applications in variety areas.
