Precise and effective control of droplet generation is critical for applications of droplet microfluidics ranging from materials synthesis to lab-on-a-chip systems.
Capsules were formed through a reaction of sodium alginate, carried in the water phase, and calcium ions, carried in the oil phase, to create a cross-linked membrane of calcium alginate surrounding a droplet. An increase in the flow rate of water had a positive correlation on the size of ...
Flow-focusing droplet generation commonly occurs at dripping or jetting regimes, with significant differences in sensitivity to the design parameters and observed performance23. Consequently, generation regime prediction is integral to accurate performance prediction of droplet generators. To achieve this, neu...

In this study, we present a passive microfluidic platform for water-in-water droplet generation. Our platform consists of a conventional flow focusing microfluidic device utilizing a microneedle inserted into the inlet of the disperse phase. The microneedle in our system helps prevent the disperse pha...

Here, we show that long-term exposure of PDMS based microfluidic droplet generation systems to water can reverse their characteristics such that they generate oil-in-water droplets instead of water-in-oil droplets. The competition between two oil columns
