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 ...Graziani, Gabriela +3 more

FT-IR spectroscopy of solid surfaces
Journal of Molecular Structure, 1984Abstract 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 ...

Absorption Anomalies in Ratio and Subtraction FT-IR Spectroscopy
Analytical Chemistry, 1998Subtraction and ratioing of strong absorption bands in Fourier transform infrared (FT-IR) spectroscopy produces anomalous absorption errors. One source of error is the instability in the wavenumber scale of the FT-IR spectra. The possible causes of this error are explored.

Characterization of Paracoccidioides brasiliensis by FT-IR spectroscopy and nanotechnology
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2016Paracoccidioides brasiliensis, the etiological agent of paracoccidioidomycosis, is a dimorphic fungus existing as mycelia in the environment (or at 25°C in vitro) and as yeast cells in the human host (or at 37°C in vitro). Because mycological examination of lesions in patients frequently is unable to show the presence of the fungus and serological ...

The solution structure of concanavalin A probed by FT-IR spectroscopy
Biochimica et Biophysica Acta (BBA) - Protein Structure and Molecular Enzymology, 1988The secondary structural properties of various forms of concanavalin A in solution were investigated by Fourier-transform infrared spectroscopy in the Amide I region. As in the crystal, the solution structure of the native protein consists mainly of antiparallel beta-sheet.

New Method for Pollen Identification by FT-IR Spectroscopy
Applied Spectroscopy, 2003A new methodology for identification of pollen was developed based on FT-IR spectroscopy. Pollen samples of twenty different plant species were collected and the diffuse reflectance infrared Fourier transform (DRIFTS) and KBr pellet spectra were recorded. Libraries of spectra were created.

FT-IR spectroscopy as a sentinel technology in earthworm toxicology
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2014FT-IR spectroscopy is a useful tool for determining the biomolecular profile of micro-samples of body fluids such as coelomic fluid of earthworms. The present study focuses on the usefulness of the earthworm (Perionyx sansibaricus) coelomic fluid for observing pathologically induced biochemical changes.

The Use of FT-IR Spectroscopy in Microtechnologies
1997Analytical studies accompanying the development of microtechnological production methods can be carried out by means of e.g. FT-IR spectroscopy. The chemical reactions taking place during various dry chemical etching processes of silicon can be observed precisely.

FT-IR and Raman Spectroscopy of C58BN
1997The standard electric arc generator was used to prepare fullerenes substitutionally doped on the surface with boron and nitrogen. The material is a unique case of a molecular crystal of high symmetry, consisting of molecules of extremely low C s symmetry. FT-IR and FT-Raman spectra of the C58BN were measured in the spectral region 2000™30 cm™1 and over
