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.

New imaging technique uses photonics for early diagnosis of bowel cancer

Early intervention could prevent many of the 160,000 deaths from colon cancer in Europe each year. Colonoscopies, the gold standard for spotting bowel cancer early, can still miss up to 20% of precancerous cells.

U.K. to roll out the largest genetic study on chronic fatigue syndrome

Fatigue is the feeling of constant tiredness or weakness, which can affect anyone. In worse cases, people develop a condition called myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). This condition is debilitating and lacks a universally accepted definition, cause, diagnosis, and even treatment.
