Controlling surface wettability using visible light is highly attractive for a range of liquid separation technologies. Here, Varanasi, McKinley and colleagues fabricate dye-sensitized photocatalytic TiO2surfaces on which liquid droplet motion can be externally manipulated by visible light illumination.
