Abstract: An example device includes a substrate having a first surface, an electrowetting force generation layer above the first surface, and a nanostructure layer formed above the electrowetting force generation layer, the nanostructure layer having nano-fingers formed thereon. The electrowetting force generation layer is to generate an electrical field to selectively move at least one reactant on the nano-fingers of the nanostructure layer.
