Oil-Powered Lab-on-a-Chip

Jul-27-18 A reusable lab-on-a-chip system manipulates fluids by floating them on acoustic waves in oil.

Developed by a team from Duke University, the chip is an evolution of previous versions, which can be degraded by a build-up of proteins and certain reagents. To offer a more effective tool, the Duke chip features a thin layer of inert oil that prevents the samples from leaving traces behind. An array of piezoelectric transducers underneath the oil vibrate to create sound waves, which can be controlled by the researchers to create dimples in the oil for the sample droplets to flow along.
