Researchers at the University of Michigan have found a way to control the movement of tiny droplets of fluid in a microelectromechanical (MEMS) device—with sound. The scientists use several musical tones to move droplets along different channels on a chip. By combining tones or applying them at appropriate times, they can move liquids along multiple channels and even mix, split, and sort the liquids.

The advance, published this week in Proceedings of the National Academy of Sciences, holds promise for making microfluidic devices compact and simple. Microfluidic devices are glass or plastic chips with etched channels through which you can maneuver nano- or even picoliters of liquids. Thousands of chemical or biological reactions can be performed on the chips simultaneously, promising to speed up medical diagnostics, chemical synthesis, and drug discovery.
