Combining Surface Plasmon Resonance (SPR) Spectroscopy with Surface-Enhanced Raman Scattering (SERS)
Analytical Chemistry, 2011The simultaneous measurement of surface plasmon resonance (SPR) spectroscopy and surface-enhanced Raman scattering (SERS) on flat metallic surfaces is demonstrated on a relatively simple experimental setup based on the Kretschmann configuration. This setup requires only minor modifications to standard Raman microscopes, and we show that it can be ...

Imaging of macrophages by Surface Enhanced Raman Spectroscopy (SERS)
Biomedical Spectroscopy and Imaging, 2013BACKGROUND: Fluorescent dyes attached to gold nanoparticles have been shown to be efficient SERS nanosensors in studies on intracellular composition. OBJECTIVE: The cells of macrophages were incubated with gold nanoparticles (45 nm of the diameter) with the attached three fluorescent dyes, i.e. rhodamine 6G, rhodamine B or green malachite.

Surface-enhanced Raman spectroscopy (SERS) in cultural heritage
Analytical Methods, 2017Surface-enhanced Raman spectroscopy (SERS) has been increasingly used in the last decade for the identification of organic colourants in works of art. 'Surface-enhancement' is the giant increase in Raman scattering intensity experienced by organic molecules adsorbed on atomically rough metallic surfaces.

ACS Nano, 2009
We report on a new analytical approach to intracellular chemical sensing that utilizes a surface-enhanced Raman spectroscopy (SERS)-enabled nanopipette. The probe is comprised of a glass capillary with a 100-500 nm tip coated with gold nanoparticles. The fixed geometry of the gold nanoparticles allows us to overcome the limitations of the traditional ...

Applications of surface-enhanced raman scattering (SERS) spectroscopy in biochemistry
Fresenius' Zeitschrift für analytische Chemie, 1984These results demonstrate that SERS spectroscopy creates a new and powerful method to study the vibrational behaviour of biomolecules at rather dilute aqueous solutions down to 10−7M.

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
