Using waves to move droplets

Controlling individual droplets leads to more efficient self-cleaning surfaces and lab-on-a-chip implementations. University of Groningen professor Patrick Onck and colleagues from Eindhoven University of Technology have shown that this is possible by using a technique named mechanowetting. The researchers report a way of transporting droplets by using transverse surface waves, which even works on inclined or vertical surfaces. The research was published in Science Advances on 14 June.
