Inks and paints are everywhere in the world around us. As well as for writing and printing, these materials are also used for protection against the elements and aesthetic reasons. These substances ...

Near-infrared spectroscopy (NIRS) is a noninvasive method used to monitor changes in hemoglobin concentration and oxygen levels in the body. This technique involves passing near-infrared light, ...

To investigate how melanin affects the accuracy of near-infrared spectroscopy (NIRS) measurements, researchers correlated the melanin levels of 35 adults with a diverse range of skin tones, measured ...

Coupling mid-infrared “idler” photons with near-infrared “signal” photons enables cheaper, smaller and more efficient machines for uses such as greenhouse gas monitoring to medical diagnostics.

Virtually every scientific field has made strides by harnessing light to study the properties of substances. This technique, called spectroscopy, has countless research applications, and innovations ...

Infrared vibrational spectroscopy could enable the production of high-resolution maps of molecules inside live cells and cell organelles. A new study from Helmholtz-Zentrum Berlin (HZB) and Humboldt ...

Researchers in Brazil’s Amazonas state are testing easy-to-use scanners that can help them identify animal species they come across in the wild, Mongabay contributor Miguel Monteiro reported in June.

This paper explores the differences and similarities between Raman and infrared spectroscopy in regard to unknown material identification and reaction monitoring. While these techniques share ...
