Abstract
Wettable structures that retain liquid layers are defined at surfaces of substrates. The wettable structures include grooves or ridges that are spaced apart by between 10 nm and 10 μm and can be defined in substrate or in a layer formed on a surface of the substrate. In typical examples, wettable structures are defined with hydrophobic materials or at hydrophobic surfaces and produce hydrophilic surfaces.
