A type of worm-like nanorods was successfully synthesized through conventional gold nanorods reacting with Na 2S 2O 3 or Na 2S. The generated worm-like gold nanorods comprise shrunk nanorod cores and enwrapped shells. Therefore, a gold–gold sulfide core–shell structure is formed in the process, dist...
