Abstract
Systems and methods are provided for producing isolated microfluidic droplets. In one aspect, a microfluidic system comprises a droplet isolation device and an injection system. The droplet isolation device includes at least one isolation unit and at least one capillary valve. The isolation unit has at least one chamber configured to receive at least two different aqueous solutions without mixing prior to entering the at least one chamber based at least in part on pressure levels of the at least two different aqueous solutions. The injection system includes an aqueous inlet, a non-aqueous inlet, a bypass outlet, a working fluid outlet, and a loading chamber. The injection system is configured to allow for a predetermined amount of each of the at least two different aqueous solutions to be delivered to the droplet isolation device sequentially.
