One-pot synthesis of noble metal nanoparticles and their ordered self-assembly nanostructures

Abstract

In this communication, we report the one-pot synthesis of noble-metal nanoparticles and their concurrent assembly into ordered nanostructures. Sodium dodecyl sulfate (SDS) and triethylene glycol monododecyl ether (C₁₂EO₃) surfactant mixtures formed highly viscoelastic fluids, reflecting the presence of long, wormlike micelles which can be used as a template for making ordered nanostructures via a controlled in situ synthesis of silver and platinum nanoparticles. The simple and versatile approach based on in situ reduction of metal ions opens a new avenue for the development of self-assembled regimented structures by noble-metal nanoparticles.
