IR spectroscopy, or infrared spectroscopy, is an analytical technique used to identify and study chemical substances based on their interaction with infrared radiation. It measures the absorption of ...

Researchers have developed a low-cost method for the analysis of interfacial molecules by combining ATR-IR with precise gap-control and multi-variate data analysis. A novel spectroscopic method ...

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

Controlling a molecule is not always simple. For instance, the precise arrangement of electrons in an organic molecule determines the wavelengths of light it can absorb; this can be challenging to ...

Scientists captured clear images of biomolecules in single live cells in water for the first time using infrared (IR) transmission imaging. The IR technique enables researchers to measure the mass of ...

If you were to use infrared (IR) transmission microscopy, you would appreciate its chemical quantification abilities—unless your object of study was a hydrated cell. In that case, you might complain ...

Imaging live cells without disrupting their natural behavior or damaging their structures is one key challenge in biomedical optics, and has been tackled in multiple ways. A project at NIST has now ...

Atomic force microscopy has long relied on the ability to acquire nanoscale chemical information while simultaneously characterizing nanomechanical properties. This article explores a new means of ...

Photothermal AFM-IR is a highly effective method for nanoscale chemical analysis, ideally suited to the stringent requirements of semiconductor research and production. By integrating the spatial ...
