Forming highly ordered arrays of functionalized polymer nanowires by dewetting on micropillars

1D nanostructures are of great interest for numerous applications: a simple and low-cost process to generate large arrays of polymer nanowires by dewetting aqueous polymer solution on an array of micropillars is developed. These nanowires are typically less than 10 nm in lateral size and can be functionalized by incorporation of molecules or nanoparticles such as quantum dots (see figure).
