surface-enhanced Raman scattering News
Raman Scattering Helps Ensure Safety of Stem Cell Therapies
NEW BRUNSWICK, N.J., Nov. 12, 2019 — A research team at Rutgers University has developed a biosensor technology that could benefit applications for the treatment of neurological disorders through stem cell therapy. The hybrid biosensing platform consists of an array of ultrathin...
Handheld Scanner Roots Out Brain Tumor Traces
NEW YORK, Sept. 5, 2014 — A new Raman laser scanner could help surgeons more effectively remove cancerous brain tumors.
Roll-to-Roll Nano Sensors Enhance Manufacturing Opportunities
ESPOO, Finland, Feb. 7, 2014 — Roll-to-roll mass manufacturing is a key technology in low-cost disposable photonic sensor production, which could pave the way for new business and job opportunities, particularly for small and medium enterprises. Photosens, a European consortium...
Grant Funds Photon Control’s Raman Research
BURNABY, British Columbia, Oct. 15, 2013 — Photon Control R&D Ltd., the research and development partner of optical sensors maker Photon Control Inc., has received an Engage grant from the Natural Sciences & Engineering Research Council of Canada (NSERCC) to collaborate with Dr....
Raman Overcomes Challenges for Industry
Sep 1, 2013 — Raman spectroscopy is becoming increasingly prevalent in commercial applications. Challenges include making remote measurements of chemical species in high-pressure or high-temperature environments while customers demand compact instrumentation with...
SERS, Nanoprobes Seek to Detect Infections Early
DURHAM, N.C., June 21, 2013 — Nanoprobes used in conjunction with surface-enhanced Raman scattering (SERS) can be used to reveal a specific molecular marker’s optical fingerprint. The work is a proof-of-principle approach to using light to detect infections before patients...
SERS Susses Out Salmonella
ATHENS, Ga., April 11, 2012 — In the future, even the smallest traces of salmonella and other foodborne pathogens may be easily detected using a technology known as surface-enhanced Raman scattering, or SERS.
Research at the Nanoscale Boosts Green Photonics
Dec 1, 2011 — Improving the efficiency of thin-film solar cells is a key challenge, and some believe that nanophotonics could be the answer. Nanophotonic structures give us better control over light, enabling us to manipulate it in ways never seen before...
Sensor Design Boosts Raman Signals
PRINCETON, N.J., March 22, 2011 — An extremely sensitive Raman sensor promises to provide new ways to detect a wide range of substances, from tell-tale signs of cancer to hidden explosives. The sensor, developed at Princeton University, relies on a completely new architecture and...
SERS Advances Disease Diagnosis
DURHAM, N.C., March 3, 2011 — Scientists at Duke University have developed a new noninvasive optical technique that uses a laser to peer into the genetic material of cells, enabling the detection of early-stage cancer and other diseases. The method uses metallic nanoparticles...
“Smartdust” shines new light on SERS
XIAMEN, China – Layering dust onto a surface you wish to study may seem counterintuitive, but scientists in China and the US claim that their “smartdust” will enable Raman spectroscopy to be used on any surface. Surface-enhanced Raman scattering...
LEDs lead to change for some silver
OTTAWA – Adding a touch of silver can improve several photonic endeavors, such as surface-enhanced Raman scattering, surface-enhanced fluorescence and surface plasmon resonance spectroscopy. The metal amplifies the otherwise minute emissions that must be...
Graphene: The rising star in Raman spectroscopy
BEIJING – With its numerous appealing qualities, including biocompatibility, chemical inertness and abundance, graphene has long been a popular metal among chemists and physicists alike. Thanks to these properties, it has found its way into new applications...
Isolating hot spots enhances Raman results
CAMBRIDGE, Mass. – A new technique demonstrated by a Harvard group may provide environmental researchers, chemists and forensic investigators with a new tool to detect and identify trace molecules. The research combined the two separate concepts of...
Gold Nanostars Shine Bright
DURHAM, NC, Nov. 7, 2008 – Tiny gold stars, smaller than a billionth of a meter, may hold the promise for new approaches to medical diagnoses or testing for environmental contaminants. Bioengineers at Duke University have indicated that of all the shapes studied to date,...
Raman Scattering Improves When Substrates Are Adorned with Silver and Gold
Mar 1, 2007 — Gold may glitter, but silver really shines when it comes to substrates for surface-enhanced Raman scattering. SERS can augment a Raman signal by 14 to 15 orders of magnitude, which makes the technique invaluable for research. Repeatable SERS results...
