Long-range spontaneous droplet self-propulsion on wettability gradient surfaces

Abstract The directional and long-range droplet transportation is of great importance in microfluidic systems. However, it usually requires external energy input. Here we designed a wettability gradient surface that can drive droplet motion by structural topography. The surface has a wettability gra...
