Abstract:
Devices, systems, and their methods of use, for generating droplets are provided. One or more geometric parameters of a microfluidic channel can be selected to generate droplets of a desired and predictable droplet size.

Claim (Index 13):
A system for producing droplets of a first liquid in a second liquid, the system comprising:\n a) a device for producing droplets, the device comprising:\n i) a first channel having a first depth, a first width, a first proximal end, and a first distal end; \n ii) a second channel having a second depth, a second width, a second proximal end, and a second distal end, wherein the second channel intersects the first channel between the first proximal and first distal ends; \n iii) a droplet formation region, wherein the droplet formation region comprises a shelf region having a third depth and a third width, and a step region having a fourth depth, wherein the shelf region is configured to allow the first liquid to expand in at least one dimension and has at least one inlet and at least one outlet, wherein the shelf region is disposed between the first distal end and the step region; \n iv) a first reservoir in fluid communication with the first proximal end, wherein the first reservoir comprises at least one portion of the first liquid; and \n v) a second reservoir in fluid communication with the second proximal end, wherein the second reservoir comprises at least one portion of the first liquid, \n wherein the portions of the first liquid are miscible and combine at the intersection of the first channel and second channel to form the first liquid, \n b) a second liquid contained in the droplet formation region, wherein the first liquid and the second liquid are immiscible, wherein the system is configured to produce droplets of the first liquid in the second liquid.
