A team of University of Rochester scientists is using the technique of Raman spectroscopy to study two common dental plaque bacteria: Streptococcus sanguis and mutans. The relative balance of the two ...

Raman spectroscopy, a laser-based optical technique that creates a biochemical "fingerprint" of tissue samples, could dramatically improve the ability to detect head and neck cancer at an earlier ...

Why is Diffuse Reflectance Spectroscopy Used? One of the main techniques for evaluating the optical properties of materials is optical absorption spectroscopy, or UV-vis spectroscopy. Most absorption ...

Variability must be avoided for OEM instrument developers who must guarantee an answer based on the quality of a Raman spectrum. These answers are important to their customers and those influenced by ...

During light scattering, the majority of scattered light undergoes no change in frequency (or energy), in a process referred to as referred to as elastic or Rayleigh scattering. Raman spectroscopy ...
