The phenomenon of ‘dewetting’—usually considered a nuisance as it causes solids to bead up into islands, much like raindrops on glass—has been harnessed for a useful application. An A*STAR-led team has clarified how dewetting can assemble arrays of 3-D nanostructures for applications including single molecule sensing.
