Caption This video clip shows fluids flowing through the channels of a National Institute of Standards and Technology microfluidic device (made from plastic film and double-sided tape) as controlled by its latest addition: valves. The changing colors indicate the starts and stops of three different fluids as the microvalves are opened and closed. Credit Gregory A.
