TL;DR: Positive charged silver nanoparticles demonstrate superior SERS activity over negatively charged citrate reduced Ag nanoparticles for the detection of thiocyanate and perchlorate ions and are promising candidates for sensing and detection of a variety of negatively charged analytes in aqueous solutions using surface-enhanced Raman spectroscopy (SERS).

TL;DR: In this paper, the surface-enhanced Raman scattering (SERS) activity using Rhodamine 6G (R6G) as a model molecule was investigated on planar glass substrates.

TL;DR: This article is the first report of net accumulative SERS from the full-length Ag-nanoparticlefunctionalized PCFs, and recommended and recently described in a brief study forward scattering as a more suitable detection mode to unambiguously assess the SERS-active nature of PCF.

TL;DR: The high sensitivity of substrates with Ag [+] for anion detection can be attributed to the presence of two types of functional groups, amino and amide, on the nanoparticle surface resulting from UV-assisted fragmentation of BPEI chains.

TL;DR: This work quantifies polarization and angle dependence of surface-enhanced Raman scattering (SERS) intensity beyond the critical angle and Detected SERS signal polarization and scattering angle dependence are shown to be in agreement with a simple model based on excitation and radiation of a classical dipole near a lossless interface.
