Nanomaterials for Surface Enhanced Raman Spectroscopy

Nanomaterials, 2023
For many decades, Raman spectroscopy has been disregarded as an ineffective analytical tool because of the very low efficiency of “normal” Raman scattering (the typical cross-section for Raman scattering is about 11 and 8 orders of magnitude smaller than

Surface-enhanced Raman spectroscopy: nonlocal limitations [PDF]

Optics Letters, 2012
Giant field enhancement and field singularities are a natural consequence of the commonly employed local-response framework. We show that a more general nonlocal treatment of the plasmonic response leads to new and possibly fundamental limitations on ...

Breath Analysis via Surface Enhanced Raman Spectroscopy. [PDF]

ACS Sens
Breath analysis is increasingly recognized as a powerful noninvasive diagnostic technique, and a plethora of exhaled volatile biomarkers have been associated with various diseases. However, traditional analytical methodologies are not amenable to high-throughput diagnostic applications at the point of need.

Surface-enhanced Raman spectroscopy [PDF]

Analytical and Bioanalytical Chemistry, 2009
Modern analytical tools should enable highly specific identification and characterization of inorganic and organic matter with minimal effort for sample preparation. Raman spectroscopy is one such highly specific method that enables identification of molecules through their specific molecular fingerprint information.
