Abstract

The highly sensitive Surface-Enhanced Raman Scattering (SERS) substrate, via a strong localized surface plasmon resonance from efficient nanogaps, can be derived from silver nanocubes, which is self-assembled on a silver surface with 1, 2-ethanedithiol as the linkage. The existence of nanogaps between Ag nanocubes and Ag surface was verified by X-ray spectroscopy and the frequency change of plasmon resonance was corroborated by the analysis of a UV–Vis spectrophotometer. The beautiful homogeneous distribution of nanocubes on the Ag surface can be used as an effective substrate by detecting a 10-9 M rhodamine 6G solution with high sensitivity (enhancement factor 2.8 × 108), high reliability (6.6% standard deviation from measurements of 20 sites), and high precision (calibration curve with 99.9% correlation coefficient).
