A Hierarchically Ordered Array of Silver-Nanorod Bundles for Surface-Enhanced Raman Scattering Detection of Phenolic Pollutants.
A hierarchically ordered array of Ag-nanorod bundles is achieved using an inexpensive binary-template-assisted electrodeposition technique. In every bundle, many small gaps are formed between adjacent Ag-nanorods, where "hot spots" are generated. As a result, this plasmonic nanostructure exhibits SERS enhancements of approximately eight orders of magnitude with uniform and reproducible SERS signal throughout the whole chip.
