Surface-enhanced Raman spectroscopy (SERS) for trace detection: measurement parameters
2022In explosives detection, it is essential to detect the smallest traces quickly and reliably directly on site without time-consuming sample preparation. Beside other techniques like rapid testing kits, surface-enhanced Raman spectroscopy (SERS) is a very powerful tool to provide substance specific information.

Surface-enhanced Raman spectroscopy (SERS) investigations of saliva for oral cancer diagnosis
Lasers in Medical Science, 2020Saliva could be an optimal sample for non-invasive cancer detection, as it contains plenty of proteins and metabolites which can reflect the health status of an individual. Moreover, pairing it with high-sensitivity, label-free detection techniques could prove successful for early cancer diagnosis.

Surface Enhanced Raman Scattering (SERS) Spectroscopy of Guanine Derivatives
1988The discovery that Raman scattering from molecules adsorbed on metal surfaces (electrodes, colloids and island films) were enhanced by 105–106 has caused extraordinary interest and excitement in recent years1,2. What is the advantage of this Surface Enhanced Raman Scattering (SERS)? 1. The high enhancement factor of the Raman scattering intensity

Surface Enhanced Raman Spectroscopy (SERS) optical fibers for remote sensing
Novel Biophotonics Techniques and Applications V, 2019In this study, we present facile fabrication of a miniaturized remote sensing SERS platform using highly tunable Nano-Sphere Lithography (NSL) technique. Self-assembly at the air-water interface was performed and the monolayer of polystyrene spheres was transferred onto the tip of optical fibers.

Nanofluidic channel based biosensor using surface enhanced raman spectroscopy (SERS)
SPIE Proceedings, 2007The Raman scattering signature of molecules has been demonstrated to be greatly enhanced, on the order of 106-1012 times, on roughened metal surfaces and clustered structures such as aggregated colloidal gold. Here we describe a method that improves reproducibility and sensitivity of the substrate for surface enhanced Raman spectroscopy (SERS) by ...

Electrochemical surface-enhanced Raman spectroscopy (E-SERS) of novel biodegradable ionic liquids
Physical Chemistry Chemical Physics, 2013Electrochemical SERS (E-SERS) was used for the first time to study the interfacial behavior of a class of pyridinium-based biodegradable ionic liquids at a silver nanoparticle (AgNP) electrode surface. An isomeric series of ionic liquids (IL) based on 3-butoxycarbonyl-1-methylpyridinium bis(trifluoromethanesulfonyl)imide were prepared, which have ...

Expanding generality of surface-enhanced Raman spectroscopy with borrowing SERS activity strategy
Chemical Communications, 2007Surface-enhanced Raman scattering (SERS) was discovered three decades ago and has gone through a tortuous pathway to develop into a powerful diagnostic technique. Recently, the lack of substrate, surface and molecular generalities of SERS has been circumvented to a large extent by devising and utilizing various nanostructures by many groups including ...
