Abstract:
A mixing apparatus comprising:a first fluid pressure source; a second fluid pressure source; a multilayer microfluidic device comprising a reservoir layer having a first fluid input coupled to said first fluid pressure source and a fluidic delivery layer coupled beneath said reservoir layer having a first channel with a first opening therein, said reservoir layer having a second fluid input coupled to said second fluid pressure source and a said fluidic delivery layer second channel with a second opening therein; said first fluid pressure source being operative to pump fluid into said channel to form a first droplet at said first opening having a first predetermined volume; said second fluid pressure source being operative to pump fluid into said second channel to form a second droplet at said second opening having a second predetermined volume; a first contact proximate said first opening; a second contact proximate said second opening; and a power source coupled to said first contact and said second contact, said power source selectively applying electrical power to said first contact and said second contact upon the formation of said first and second droplets to mix respective first and second fluid deliveries.
