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.

Optical photothermal infrared (O-PTIR) spectroscopy is an infrared super-resolution measurement technique where a shorter ...

The review discusses innovations in quartz-enhanced laser spectroscopy, emphasizing QEPAS and LITES for improved sensitivity in trace gas sensing technologies.

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 ...

Atomic Force Microscopy (AFM) is an established nanoscale imaging technique, offering a topographic map of a surface sample high spatial resolution. The main drawback, until recently, of using AFM has ...

Attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy is an excellent tool for analyzing biofluids. A biological fingerprint can be extracted from the sample as an IR spectrum ...

Definition: Fourier Transform Infrared (FTIR) Spectroscopy is a highly specialized type of IR spectroscopy. It's the most common way IR measurements are carried out today. FTIR is known for its speed, ...
