New mechanism moving droplets at record-high speed and long distance without extra power

Description

Transporting droplets on solid surfaces at high speed and long distance, even against gravity, without additional force has been a formidable task. But a research team comprising scientists from City University of Hong Kong (CityU) and three other universities and research institutes has recently devised a novel mechanism to transport droplets at record-high velocity and distance without extra energy input, and droplets can be moved upward along a vertical surface, which has never been achieved before. The new strategy to control droplet motion can open up new potential in applications in microfluidic devices, bio-analytical devices and beyond.
