Colloidal approaches to discrete plasmonic architectures offer numerous advantages with respect to lithography; however, scale‐up, purity, and yield has been challenging. Reversibly controlling surface interactions throughout aqueous assembly affords methods that address these challenges. The false‐color image illustrates the crude product of soluble, compositionally discrete Au nanorod (50 nm × 20 nm) assemblies. Their stability affords post‐assembly processing–including separation of discrete structures (e.g., Au nanorod pairs)–and silica encapsulation, where the latter exhibits thermal stability in excess of 700 °C.
