Abstract
A device for performing a microfluidic assay on a chip comprising, a microfluidics chip, one or more fluid receptacles on the chip for receiving a fluid, a plurality of pneumatic pumps arrayed on the chip, each pump having a discharge channel leading to a rectifier on the chip, and a reaction chamber in fluid communication with each of the rectifiers, wherein a pressure on the pressurized fluid source drives fluid from the fluid receptacle into the incoming fluid channel connecting the fluid receptacle to the pump, through the pump and into the discharge channel, through the discharge channel to the rectifier, and through the rectifier into the reaction chamber, wherein the pump is configured to generate droplets of a pre-determined size, wherein the rectifiers prevent backflow of the droplets, and wherein droplets are combined in the reaction chamber, the chamber facilitating an assay being performed on the chip.
