surface-enhanced Raman spectroscopy News
SERS-Based Nanosensor Detects Pesticides on Fruit
SOLNA, Sweden, June 13, 2022 — Researchers at the Karolinska Institutet in Sweden developed a nanosensor based on surface-enhanced Raman spectroscopy or scattering (SERS). The proof-of-concept method uses flame-sprayed silver nanoparticles to increase the signal of chemicals. SERS can be used to increase the diagnostic signals of biomolecules on a metal surface by more than 1 million times. It has been used in chemical and environmental analysis to detect biomarkers for various diseases. High production costs and
Ghent Researchers, SERS, Perform and Demonstrate Sensitive Protease Monitoring
GHENT, Belgium, Sept. 11, 2020 — Researchers at Ghent University have detected protease using surface-enhanced Raman spectroscopy (SERS) performed with a tiny waveguide. The work moves toward real-time, label-free, lab-on-a-chip protease monitoring, which could offer a...
Team Bridges Nanocatalyst Size Gap for Real-Time Data
COLUMBIA, S.C., and HOUSTON, June 9, 2014 — Obtaining real-time reaction information from nanocatalysts has long impeded attempts to describe them in detailed kinetic behavior. But a team from the University of South Carolina and Rice University has discovered just how to do it. The...
Spaghettilike surface makes stronger SERS sensor
ZURICH, and LIVERMORE, Calif. – Spaghettilike arrays of gold-coated metallic carbon nanotubes can amplify the signals of surface-enhanced Raman spectroscopy (SERS) enough to perform analyses that are more reliable, sensitive and cost-effective. Previously, the detection limit of...
Spaghetti-like Surface Makes Stronger SERS Sensor
ZURICH & LIVERMORE, Calif., Aug. 30, 2013 — An innovative plasmonic sensor amplifies the signals of surface-enhanced Raman spectroscopy (SERS) using a novel substrate based on carbon nanotubes with metal-coated tips. Scientists at ETH Zurich and the Lawrence Livermore National Laboratory...
Hybrid Fabrication Makes Better Plasmonic Nanostructures for SERS
Aug 1, 2013 — Monolithic hierarchical plasmonic nanostructures improve results from surface-enhanced Raman spectroscopy. Plasmonic nanostructures of gold and silver have emerged as attractive nanomaterials because of their small size, corrosion resistance,...
Nanostars Seen as Superior for SERS
HOUSTON, March 29, 2012 — Synthesized starfruit-shaped gold nanorods could strengthen applications that rely on surface-enhanced Raman spectroscopy.
SpectraFluidics Secures Contract
SANTA BARBARA, Calif., Dec. 14, 2011 — SpectraFluidics Inc. received a $1.3 million contract from the US Department of Homeland Security, Transportation Security Administration to develop and validate a system that detects homemade explosives. The company develops and manufactures vapor...
Light Shed on Mystery of Raman Signal Enhancement
BERKELEY, Calif., April 25, 2011 — Investigations into the chemical basis of Raman signal enhancement have resulted in a path to complementary data from SERS and other Raman-based experiments. SERS (surface-enhanced Raman spectroscopy) capitalizes on the enhancement of a Raman...
Creating nanostructures with shadows
BERKELEY, Calif. – From out of the shadows, researchers at the University of California, Berkeley, have built nanostructures that might lead to more efficient solar power. Another potential applicati...
Sniffing out threats with light
Dec 1, 2009 — It isn’t time to retire bomb-sniffing dogs – yet. However, that scenario is closer to happening, thanks to advances in surface-enhanced Raman spectroscopy, hyperspectral imaging and other photonics technologies. Armed with these, police and military...
The art of SERS
CHICAGO – Surface-enhanced Raman spectroscopy (SERS) could help identify forged artworks. Researchers are using it to analyze paintings by 19th-century artist Mary Cassatt and the pastels she used to identify whether the materials were natural, synthetic or...
Nanoscale ‘Pins’ Enhance SERS
May 1, 2007 — Surface-enhanced Raman spectroscopy (SERS) is still a young technique, but it shows promise for elemental and chemical analysis in the semiconductor and biology fields, among others. It has been well established that using silver or gold nanoscale...
