Applications of Fourier transform infrared spectroscopy, Fourier transform infrared microscopy and near‐infrared spectroscopy to cancer research [PDF]
Journal of Spectroscopy, 2003 Glycogen levels in human lung and colorectal cancerous tissues were measured by the Fourier transform (FT‐IR) spectroscopic method. Reliability of this method was confirmed by chemical analyses of the same tissues used for the FT‐IR spectroscopic measurements, suggesting that this spectroscopic method has a high specificity and sensitivity in ...

Classification of gallstones using Fourier-transform infrared spectroscopy and photography
Biomaterials Research, 2018 Background Gallstones have conventionally been classified by gross inspection into 4 categories: cholesterol gallstones, black pigment (calcium bilirubinate) gallstones, brown gallstones, and mixed gallstones that contain both cholesterol and calcium ...

Mid-infrared feed-forward dual-comb spectroscopy at 3 $μ$m [PDF]
Proceedings of the National Academy of Sciences of the United
States of America 116, 3454-3459 (2019), 2018 Mid-infrared high-resolution spectroscopy has proven an invaluable tool for the study of the structure and dynamics of molecules in the gas phase. The advent of frequency combs advances the frontiers of precise molecular spectroscopy. Here we demonstrate, in the important 3-{\mu}m spectral region of the fundamental CH stretch in molecules, dual-comb ...
