Engineering atomic structures at metal surfaces represents an important step in the development of novel nanomaterials and nanodevices but relies predominantly on atomic/molecular beam epitaxy under ultrahigh vacuum conditions where controlling the deposition processes remains challenging. By using solution-borne nanosized gold clusters as a precursor here we develop a wet deposition protocol to the fabrication of atomically flat gold nanoislands so as to utilize the dynamic exchange of surface-active molecules at the liquidmetal interface for manipulating the growth kinetics of ultrathin metallic nanostructures. While remarkable shape and size selection of gold nanoislands is observed our experimental and theoretical investigations provide compelling evidences that organic adsorbates can impart a bias to the island orientation by preferred adsorption and alignment and intervene in the assembly and disassembly of adatom islands by complexing with Au adatoms. This approach offers a simple solution to regulate atomic layer growth of metals at ambient conditions.
