Researchers from Tokyo Metropolitan University have measured how oxygenated hemoglobin levels in the blood change in infants' brains in response to touch. Using spectroscopy methods with external ...

When things vibrate, they make sounds. Molecules do too, but at frequencies far beyond human hearing. Chemical bonds stretch, bend, and twist at characteristic rates that fall in the infrared region ...

The team found the same peaked response in oxygenated hemoglobin levels in infants of different ages over their first year. Tokyo, Japan – Researchers from Tokyo Metropolitan University have measured ...

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 ...

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 ...

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 ...

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 ...
