Filling Microfluidic Devices There's an art to filling microfluidic devices. It's easy to create air bubbles that limit or eliminate the functionality of the device. With a bit of care and some patience, though, it is possible to fill the devices fully with fluid. The process is to introduce fluid into one opening and allow capillary action to "suck" the fluid through the rest of the device. The device below has five connections; we are going to add fluid through the leftmost one. First, we place a small droplet of deionized (DI) water over the hole. This ensures that when we insert the fluid-filled pipette tip, we do not push air into the channel.
