Investigation of simultaneously existed Raman scattering enhancement and inhibiting fluorescence using surface modified gold nanostars as SERS probes

Scientific Reports, 2017
One of the main challenges for highly sensitive surface-enhanced Raman scattering (SERS) detection is the noise interference of fluorescence signals arising from the analyte molecules. Here we used three types of gold nanostars (GNSs) SERS probes treated

Periodic metal resonator chains for surface enhanced Raman scattering (SERS) [PDF]

Journal of Applied Physics, 2021
A periodic arrangement of chains of gold disks shows pronounced plasmonic grating resonances. These have a clear impact on the surface enhanced Raman-scattering (SERS) signal from 4-methylbenzenethiol molecules, which form self-assembled monolayers on the gold surface: Besides a clear polarization dependence, the SERS-spectra also exhibit a maximum ...
