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.

Researchers have long sought to develop multifunctional stealth materials capable of evading detection across different parts of the electromagnetic spectrum. However, achieving compatible stealth ...

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 ...

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 ...

Photonic systems are quickly gaining traction in many emerging applications, including optical communications, lidar sensing, and medical imaging. However, the widespread adoption of photonics in ...

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 ...

Photothermal AFM-IR, commonly referred to as AFM-IR, is an analytical technique used to understand the chemistry of a material at the nanoscale. It combines the nanoscale spatial resolution of atomic ...
