Table 2.

The detailed information for generating the core-shell microcapsules with the PDMS microfluidic device. The table also shows that the PDMS microfluidic device assembled by simple hand-pressing is capable of sustaining the high pressure-driven fluid flows for generating microcapsules for hours without leaking.

Channel	Diameter	Flow rate	Experiment time	Leaking (n = 7)
Core	250 μm	300 μL h−1	3 h	No
Shell	350 μm	1.4 mL h−1	3 h	No
Oil	500 μm	8 mL h−1	3 h	No
Extraction	900 μm	8 mL h−1	3 h	No
