Surface-Enhanced Raman Spectroscopy of DNA

Journal of the American Chemical Society, 2008
We report a method for obtaining highly reproducible surface-enhanced Raman spectroscopy (SERS) of single and double-stranded thiolated DNA oligomers. Following a protocol that relaxes the DNA into an extended conformation, SERS spectra of DNA oligonucleotides are found to be extremely similar, strongly dominated by the Stokes modes of adenine.

Understanding the Surface-Enhanced Raman Spectroscopy “Background”

The Journal of Physical Chemistry C, 2009
Even 35 years after the discovery of surface-enhanced Raman spectroscopy (SERS) much remains to be learned about the phenomenon.(1-3) Despite broad consensus on the mechanism of SERS, many features remain poorly understood and in particular much less effort has been put into understanding the continuum emission called the “background” observed in SERS ...

Glyphosate Assessment by Raman Spectroscopy and Surface-Enhanced Raman Spectroscopy

Conference on Lasers and Electro-Optics, 2022
We applied Raman and SERS spectroscopy to obtain the fingerprint of glyphosate, a worldwide used dangerous pesticide. We corroborate the utility of gold nanoparticles to improve the Raman scattering, obtaining an enhancement factor of 105.

Surface-enhanced low-frequency Raman spectroscopy

Proceedings of the 2022 Conference on Lasers and Electro-Optics Pacific Rim, 2022
In this research, we for the first time demonstrated surface-enhanced low-frequency Raman spectroscopy. Low-frequency Raman scattering from a thin layered MoS2, which arises from inter-layer interaction, was highly enhanced by silver nanoparticles.

Surface-Enhanced Femtosecond Stimulated Raman Spectroscopy

The Journal of Physical Chemistry Letters, 2011
Surface-enhanced Raman spectroscopy (SERS) and femtosecond stimulated Raman spectroscopy (FSRS) have revolutionized the Raman spectroscopy field. SERS provides spectroscopic detection of single molecules, and FSRS enables the acquisition of Raman spectra on the ultrafast time scale of molecular motion.

Multiplexed Microfluidic Surface-Enhanced Raman Spectroscopy

Applied Spectroscopy, 2007
Over the past few decades, surface-enhanced Raman spectroscopy (SERS) has garnered respect as an analytical technique with significant chemical and biological applications. SERS is important for the life sciences because it can provide trace level detection, a high level of structural information, and enhanced chemical detection.

Surface enhanced raman spectroscopy

2007
The differential scattering cross-section of many molecules is greatly influenced by adsorption of these molecules at metal surfaces. This phenomenon is known in the literature as “surface enhanced Raman scattering (SERS)”. Enhancement factors as large as 105…106 have been observed.

Surface enhanced Raman spectroscopy in microchip electrophoresis

Journal of Chromatography A, 2018
Coupling microchip capillary electrophoresis to surface enhanced Raman spectroscopy (MCE-SERS) combines the high separation power of capillary electrophoresis with the capability to obtain vibrational fingerprint spectra for compound identification. Raman spectroscopy is a structurally descriptive and label-free detection method which is particularly ...
