This article aims to overview infrared (IR) spectroscopy. Simultaneously, it outlines mid-
infrared (MIR), near-infrared (NIR), and far-infrared (FIR) or terahertz (THz) spectroscopy …

In nanomechanical photothermal absorption spectroscopy and microscopy, the measured
substance becomes a part of the detection system itself, inducing a nanomechanical …

Mid-infrared spectroscopy is a sensitive and selective technique for probing molecules in the
gas or liquid phase. Investigating chemical reactions in bio-medical applications such as …

Insights into the fascinating molecular world of biological processes are crucial for
understanding diseases, developing diagnostics, and effective therapeutics. These …

Noble-metal-based nanozymes have attracted great interest as enzyme mimics because of
their unique properties. To modulate the performance and meet the requirements of practical …

Health state transitions are reflected in characteristic changes in the molecular composition
of biofluids. Detecting these changes in parallel, across a broad spectrum of molecular …

Mid-infrared chemical sensors based on quantum cascade technology offer a number of
properties surpassing conventional spectrometric techniques. In this work, we combine a …

We report on a mid-infrared (mid-IR) photothermal spectrometer for liquid-phase samples for
the detection of water in organic solvents, such as ethanol or chloroform, and in complex …

In this study, an external cavity-quantum cascade laser-based mid-infrared (IR) spectrometer
was applied for in-line monitoring of proteins from preparative ion-exchange …

Chemical imaging combines the spatial specificity of optical microscopy with the spectral
selectivity of vibrational spectroscopy. Mid-infrared (IR) absorption imaging instruments are …
