Classification: CPC B | IPC B

Claim 0:
1. An immiscible droplet generation system comprising:
a chip;
a microfluidic channel integrated into the chip;
an input fluidically coupled to the microfluidic channel to permit filing of a first fluid into the microfluidic channel;
a droplet generator integrated into the chip and fluidically coupled to the microfluidic channel, the droplet generator configured to:
generate a droplet of a second fluid, immiscible within the first fluid, and
inject the droplet of the second fluid into the first fluid when the first fluid is present in the microfluidic channel,

wherein the droplet of the second fluid is injected into the first fluid without passing through air, and wherein the droplet of the second fluid generated has a size ranging from 1 picoliter to 100 picoliters; and
a sensor integrated into the chip along the microfluidic channel downstream of the droplet generator, the sensor configured to determine a frequency at which droplets generated by the droplet generator pass a predetermined point in the microfluidic channel.
