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.

Biosensor opens up possibility of rapid, point-of-care diagnostic tool for cancer patients

Vibrational spectroscopy opens up new ways to diagnose chronic diseases

In today’s ageing population, resulting in a rising prevalence of chronic diseases such as neurodegeneration, the need for simple, non-invasive methods to diagnose or screen for important medical conditions becomes more and more relevant. Objective and cost-effective approaches capable of diagnosing early-stage disease in point-of-care clinical settings are necessary to facilitate the personalising of therapies to prevent or slow down pathology development.
