Surface enhanced Raman spectroscopy (SERS) sensors for gas analysis
The Analyst, 2010This paper presents work towards a gas sensor based on surface enhanced Raman spectroscopy (SERS). Sensitive SERS analysis of CO and N(2)O was performed using a mixed AgPd nanoparticle substrate that facilitated effective gas adsorption and strong SERS generation.

Receiver operating characteristics analysis of Surface Enhanced Raman Spectroscopy (SERS) sensors
SPIE Future Sensing Technologies, 2020Inkjet-printed surface enhanced Raman spectroscopy (SERS) sensors are fabricated on cellulose based paper or fabric substrates. These flexible sensors provides basic point-of-sampling advantages that is particularly useful in field applications. Due to the heterogeneous loading of nanoparticles on the substrate, SERS intensities inevitably vary across ...

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.
