Differentiation of Leishmania species by FT-IR spectroscopy

Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2015
Leishmaniasis is a parasitic infectious disease caused by protozoa that belong to the genus Leishmania. It is transmitted by the bite of an infected female Sand fly. The disease is endemic in 88 countries Desjeux (2001) [1] (16 developed countries and 72 developing countries) on four continents.

FT-IR spectroscopy of methylmercury-exposed mouse lung

Molecular and Cellular Biochemistry, 1995
Infrared spectroscopy which has traditionally been utilized by chemists and physicists for characterization and identification of the structural properties of chemical compounds is now becoming more relevant as a biodiagnostic tool. Recent reports suggest that arthritis and Alzheimer's disease can be diagnosed by using this technique.

FT-IR photoacoustic depth profiling spectroscopy of enamel

Calcified Tissue International, 1994
Photoacoustic Fourier transform infrared (PA-FT-IR) depth profiling spectra of the enamel of an intact human tooth are obtained in a completely nondestructive fashion. The compositional and structural changes in the tissue are probed from the enamel surface to a depth of about 200 microns. These changes reflect the state of tissue development.

FT-IR spectroscopy: a powerful tool in pharmacology

Journal of Pharmaceutical and Biomedical Analysis, 2002
In the present work we report a Fourier Transform Infrared (FT-IR) analysis performed on rat encephalon samples in the CH-OH vibrational stretching region (2400-3800) cm(-1), in order to reveal the presence of a very diffuse commercial benzodiazepine: VALIUM.

Protein Analysis by FT-IR/ATR Spectroscopy

Fourier transform infrared spectroscopy (FT-IR) is a powerful tool for the study of inorganic and organic materials. In the past years, many efforts have been put forward for the use of FT-IR in living cells and tissues, and as a diagnostic tool to study pathology in vivo, ex vivo, and in vitro, due to its peculiar advantages, which include high ...

FT-IR spectroscopy of solid surfaces

Journal of Molecular Structure, 1984
Abstract Since Fourier transform infrared (FT-IR) spectrometers offer very high sensitivity, special application methods for solids can be used in the infrared region in which weak radiation power reaches the detector. In this paper measurements of solid surfaces by photoacoustic, diffuse reflectance and emission FT-IR spectroscopy will be presented ...

ADC Errors In Quantitative FT-IR Spectroscopy

SPIE Proceedings, 1985
Analog-to-digital converters (ADCs) are an indispensible component in the electronic processing chain of modern computer-ized instruments, such as Fourier transform infrared (FT-IR) spectrophotometers. In an FT-IR spectrometer, the interferogram of a broadband source covers a wide dynamic range, on the order of 106:1.

Surface Spectroscopy Using FT-IR

2017
FT-IR is quite suitable for studying thin films (or molecular adsorbates) on a solid or liquid surface because of the high sensitivity and quantitatively great reproducibility, which perfectly matches the theoretical prediction based on electrodynamics.

Some Applications Of FT-IR Photoacoustic Spectroscopy

SPIE Proceedings, 1985
The sensitivity and speed of FT-IR make it possible to obtain the photoacoustic spectra of a variety of samples with little or no sample preparation (1,2). A typical photoacoustic (PA) detector consists of an acoustically sealed cell of small volume in which the sample under study is kept surrounded by an inert gas.
