Raman Spectroscopy News and Research

RSS

In Raman spectroscopy, a laser is used to irradiate a sample. Almost all of the light is scattered in an elastic manner, meaning no change in energy occurs. However, a small percentage of light is scattered in an inelastic manner, known as Raman scattering. This process was first observed by Indian scientist Sir Chandrashekhara Venkata Raman in 1928.

SERS Decodes Cancer's Whispers: Metabolites Reveal Tumor Communication and Potential Targets

A study conducted by pre-PhD researcher Pablo S. Valera and recently published in PNAS demonstrates the potential of surface-enhanced Raman spectroscopy (SERS) to explore metabolites secreted by cancer cells in cancer research.
