Fiber optic SERS probes, called “optrodes,” combine spectroscopy with the flexibility and versatility of fiber optic cables.

UNC postdoctoral Ajit Prakash explores how G proteins function as intracellular pH sensors and how this affects cell ...

While many people often use spectroscopy and spectrometry interchangeably, there are some subtle differences in their exact meanings and the associated experimental techniques they are used to ...

Before a spectrometer can do any useful work, it needs to be calibrated to identify wavelengths correctly. This is usually done by detecting several characteristic peaks or dips in a well-known light ...

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 ...

Near-IR spectroscopy belongs to the group of vibrational spectroscopy techniques, along with mid-infrared spectroscopy (primarily FT-IR) and Raman spectroscopy. The first near-IR spectrometers were ...

Positron Annihilation Spectroscopy (PAS) is a highly sensitive, non-destructive method for probing atomic-scale imperfections in a broad spectrum of materials, from metals and ceramics to polymers and ...

Intelligent manufacturing systems that enable real-time product releases will become commonplace in the not-too-distant future, thanks to advances in process monitoring and analytical techniques, ...

Infrared spectroscopy, which measures light absorption, provides valuable insights into the structure and conformation of biomolecules. When combined with other analytical techniques, Fourier ...

Scientists at the U.S. National Institute of Standards and Technology (NIST) have developed a new laser-based technique, which, they say, could significantly analysis of a variety of materials and ...
