Wet-chemical approach to three-dimensional gold nanocorallines: synthesis and application in surface-enhanced Raman spectroscopy.
The shape-controlled synthesis of micrometer-sized gold nanocoralline was simply realized via a wet-chemical approach. The as-prepared hierarchical gold nanocorallines (HGNs) on the solid substrate were initially applied in SERS analysis with 4-aminothiophenol (4-ATP) as the probe molecule. The HGN-modified glass substrate exhibits a higher SERS effect (one order of magnitude higher) than the aggregated gold nanoparticle ( approximately 25 nm)-modified glass substrate.
