Raman-based approach images biological processes in action

摘要

MARSEILLE, France--A fast imaging technique could improve molecular-scale understanding of the biological processes involved in the early stages of disease. The technique uses polarization-resolved coherent Raman scattering (polar-CRS) to reveal a sample's chemical makeup as well as the orientation of molecules that comprise it. The technique takes only seconds, making it possible to view the progression of disease in a living animal model at the molecular level. With further development, this technique could be used to detect early signs of neurodegenerative diseases in people.
