Metastable cationic gold nanoparticles were newly developed by the use of thiocholine bromide (TCB) as stabilizer. The gold nanoparticles electrostatically bound to DNA molecules and then underwent self-fusion into the wire-like structures. The use of TCB as a labile ligand was essential to achieve non-electrochemical plating of the non-conductive molecules.
