Research progress in cross-interface transfer of microfluidic droplets and its application
The directional transfer and accurate control of droplets in microfluidic devices is the basis and key for droplets to achieve interphase transfer across the liquid-liquid interface,which has gradually become one of the independent unit operations in microfluidic technology,showing broad application prospects in many fields such as capsule preparation,drug delivery,particle sorting.Compared with the traditional macroscopic method,the manipulation of droplet transfer between different phases could avoid the additional product separation and cleaning steps.Moreover,microfluidic devices could be integrated into a microfluidic system to realize the continuous operation.In this paper,the research progress of the methods and application of droplet cross-interface transfer in microfluidic devices are reviewed.The prospects for future research direction in the field are also given.
