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 ...

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 ...

Astronomers from the Aryabhatta Research Institute of Observational Sciences (ARIES) in India and elsewhere have conducted a ...

NIR spectroscopy concerns the analysis of how NIR light and matter interact. In spectroscopic analysis, light is determined by the wavelength, not by the applied energy. The wavelength of light is ...

How can you tell if fruit has reached its optimal ripeness without picking it, touching it or carrying out any test that might damage it? A research team from the Department of Analytical Chemistry ...

Researchers have shown that near- and mid-infrared spectroscopy of leaves can reliably reveal a fruit’s ripeness without ...
