This videos shows aqueous droplet generation at very high throughput (1000droplet/s). Two aqueous flow streams are fused at the droplet formation. In this example, the reaction between the two phase will start only when the droplet is formed.

It is also possible to adjust the two aqueous flow rate in order to modulate the concentration of reagents inside each droplet.

Therefore, each droplet become a single and unique bioreactor where material can evolve and be manipulated.
