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, ...

Infrared spectroscopy (IRS) is a technique used to analyze individual substances in isolation or a mixture, using their spectral information. IRS is based on the measurement of the wavelength and ...

Infrared (IR) spectroscopy is a frequently used technique for the structural analysis of simple and complex molecules. It has wide applications in both the qualitative and quantitative analysis of ...

PiFM and PiF-IR are the next generation of infrared spectroscopy techniques. PiFM brought a major shift to atomic force microscopy by adding chemical mapping capabilities. PiF-IR, its sister technique ...

Infrared and Raman spectroscopies can observe different types of molecular vibrations. Using both methods on a compound provides a more complete molecular picture than either alone. But the two ...

What is Surface-Enhanced Infrared Absorption (SEIRA) Spectroscopy? Surface-enhanced infrared absorption (SEIRA) spectroscopy is an advanced analytical technique that combines the principles of ...

It has become harder and harder to assess the real value of a gemstone since the emergence of synthetic diamonds, treated diamonds and nearly perfect imitates. Infrared spectroscopy is an elegant way ...

A blood test using infrared spectroscopy can be used to diagnose two types of cancer, lymphoma and melanoma, according to a study led by Georgia State University. Researchers used mid-infrared ...

Photothermal AFM-IR combines atomic force microscopy and infrared spectroscopy to reveal chemical heterogeneity and ...
