Abstract
The invention generally relates to methods and systems for manipulating droplet size. In certain aspects, the invention provides methods for manipulating droplet size that include forming droplets of aqueous fluid surrounded by an immiscible carrier fluid, and manipulating droplet size during the forming step by adjusting pressure exerted on the aqueous fluid or the carrier fluid.
Claims22
1-17. (canceled)
A microfluidic apparatus comprising:
- a plurality of microfluidic circuits, each circuit comprising:
- a first fluid channel comprising a first resistance and a first fluid;
- a second fluid channel, comprising a second resistance and a second fluid that is immiscible with the first fluid;
- a junction where the first fluid channel and the second fluid channel meet such that a plurality of droplets are formed;
- and
- an outlet channel that exits the junction and receives the droplets;
- wherein the first and second resistances of the microfluidic circuits are configured such that variation in pressure exerted on the first fluid in each circuit results in a change in flow rate of the second fluid and a change in a dimension of the droplets.
4 more elements
A microfluidic apparatus comprising:
- a plurality of microfluidic circuits each configured to produce droplets;
- and
- a regulator operably associated with each microfluidic circuit that controls pressure exerted on a first fluid that causes a change in flow rate of a second fluid, and adjusts a dimension of the droplets from each microfluidic circuit.
