A simple chemical route to fabricating highly linear, well‐aligned and unbranched one‐dimensional arrays of silver nanoparticles with ultra‐high aspect ratios is demonstrated. Starting with a polydisperse nanoparticle material, the application of ultrasound was found to promote digestive ripening and induce a thiolate‐driven self‐assembly process. The assembly method discovered has been extended to other systems, with initial findings showing the successful templating of gold nanoparticles into chains using Cu(I)‐thiolates. This opens the possibility of a generic route which can be applied to many nanoparticle systems.
