This property also endows the surface with pinning-free evaporation, which in turn has been exploited for analyte concentration enrichment for Surface Enhanced Raman Spectroscopic applications and ...

However, the thinner silver shell may affect their plasmonic properties, which influences the overall SERS enhancement. Figure 3C and d present the Raman spectra of the Au@Ag nanoparticles with 40 nm ...

This localized enhancement led to the initial interest in the use of Raman spectroscopy to probe the specific environment of the nanoparticle. The authors have no relevant affiliations or ...

2013;8(8):1335-1351. Spontaneous Raman spectroscopy has, therefore, already been demonstrated to be a chemically specific method for investigating nanoparticle interactions and to probe the ...
