Near-IR absorption spectrum of dichloromethane showing complicated overlapping overtones of mid IR absorption features. Near-infrared spectroscopy (NIRS) is a spectroscopic method that uses the near-infrared region of the electromagnetic spectrum (from 780 nm to 2500 nm). [1]

Near-infrared spectroscopy (NIR) is a widely used rapid alternative to time-consuming, solvent intensive, wet-chemistry methods and chromatographic techniques. Rely on NIR to quickly verify incoming raw materials, monitor reaction progress, and quantify final products with ease.

The development of near-infrared (NIR) fluorescent probes over the past few decades has changed the way that biomolecules are imaged, and thus represents one of the most rapidly progressing areas of research.

May 1, 2023 · Near infrared (NIR) fluorescent probes have the advantages of low background interference, strong tissue penetration and small tissue damage. Many fluorescent dyes, such as BODIPY, cyanine, rhodamine and coumarin, have been used as fluorophores to design NIR fluorescent probes.

Nov 1, 2023 · Probes that emit fluorescence in the NIR-II range exhibit deeper penetration and reduced photon scattering without causing damage in biosamples, thereby enabling imaging with higher SBRs than NIR-I fluorescent probes.

Jul 27, 2021 · Optical imaging systems that employ near-infrared (NIR) fluorescent probes to detect protease activity offer clinical promise, both for early detection of cancer as well as for the assessment of personalized therapy.

Near-infrared (NIR) spectroscopy is a non-destructive analytical tool that provides solutions from drug development to the QA/QC lab, and in at-line, on-line, or continuous manufacturing processes.

Feb 5, 2025 · Leveraging the superior penetration capabilities, negligible autofluorescence, and extended fluorescence emission wavelengths, NIR-II fluorescent probes significantly enhance the signal-to-noise ratio (SNR) of in vitro detection (IVD) and the temporal resolution of …
