What is Surface-Enhanced Raman Scattering (SERS)? Surface-enhanced Raman scattering (SERS) is a powerful analytical technique that significantly enhances the Raman scattering signal of molecules ...

SERS offers a greater signal-to-noise ratio than ordinary Raman spectroscopy, so it is useful in single-molecule detection or detecting analytes in low concentrations. Improvement of the spectroscopic ...

Researchers have developed a new compact Raman imaging system that is sensitive enough to differentiate between tumor and ...

The ability of Raman spectroscopy to identify molecular-level spectral fingerprints has made it an attractive route to diagnostic information and identification of early-stage tumors, especially in ...

Visualization of Tip-Enhanced Raman Spectroscopy (TERS): This diagram illustrates the interaction of a laser beam with a sample surface through a sharp metallic tip. The red laser light excites the ...

When an ecological disaster releases toxins into the environment, extensive sampling and analysis is vital to ensure the health and safety of the people affected. Surface-enhanced vibrational ...
