Improving droplet encapsulation of a single-cell and single-bead to increase pharmacological assay throughput.
Encapsulation of a single cell and bead reagent is of critical importance when conducting droplet based analysis of single cells. Currently, droplet encapsulation is not well controlled. One-cell-one-bead encapsulation efficiency is limited by an uncontrolled random droplet encapsulation of cells and beads (0.1% 1 in 100 droplets). This low droplet encapsulation efficiency hinders the realization of high throughput droplet based experiments.
UCI researchers have developed a microfluidic droplet encapsulation method to efficiently encapsulate one-cell and one bead. By designing a microfluidic device with controllable fluid flow and a high force liquid-liquid interface, one-cell one-bead droplet encapsulation efficacy can be well controlled. Utilizing the invented technology, it has been shown that a significantly large increase in droplet encapsulation efficiency can now be readily achieved. Whereas existing techniques only provide random encapsulation governed by Poisson statistics, the improved encapsulation efficiency in this invention enhances the ability to perform single cell genomics and proteomics on a microfluidic platform.
