Charged superamphiphobic surface propels water, blood and other liquids up vertical slopes and even upside down
Defying gravity and without apparent energy input, droplets race up vertical walls, travel in circles or even roll upside down – all thanks to a superamphiphobic surface. The material can be programmed to precisely control droplets’ movement, which could find applications in microfluidics and water harvesting.
