FTIR-spectroscopy in microbial and material analysis

International Biodeterioration & Biodegradation, 1998
Abstract The investigation of the development and the properties of biofilms is difficult because classical microbiology does not offer non-destructive methods other than microscopical observations. This paper discusses the use of different Fourier transform infrared spectroscopy (FTIR-spectroscopy) techniques as a means to investigate microorganisms

Using Transient FTIR Spectroscopy to Probe Active Sites and Reaction Intermediates for Selective Catalytic Reduction of NO on Cu/SSZ-13 Catalysts

ACS Catalysis, 2019
A Cu/SSZ-13 catalyst containing predominately Z2Cu sites is prepared. Using FTIR spectroscopy, two nonsteady-state measurements, (1) continuous NO titration of an NH3 saturated catalyst and (2) intermittent NO on/off cycles during quasi-steady state (i.e.

Application of FTIR Spectroscopy to Analyze RNA Structure

2020
Fourier transform infrared (FTIR) spectroscopy has been widely used for the analysis of both protein and nucleic acid secondary structure. This is one of the vibration spectroscopy methods that are extremely sensitive to any change in molecular structure.

FTIR Emission spectroscopy of surfaces

Journal of Molecular Structure, 1982
Abstract A number of vibrational spectroscopic techniques are available For the study of surfaces, such as ATR, IR reflection-absorption, IR emission, etc. Infrared emission is hardly used, although interesting applications are possible now due to the high sensitivity of Fourier transform IR (FTIR) spectrometers. Two examples, where infrared emission

Industrial applications of FTIR spectroscopy

SPIE Proceedings, 1994
The position and advantages of FT-IR among other analytical techniques are discussed, especially in the surface and microanalyses. Two typical examples of FT-IR applications being done recently in our laboratories are presented. Molecular orientation and surface morphology of mechanically rubbed polyimide films used for the alignment layer of liquid ...

Secondary Structure of Monoamine Oxidase by FTIR Spectroscopy

Biochemical and Biophysical Research Communications, 1995
The secondary structure of human monoamine oxidase A and bovine monoamine oxidase B has been investigated by Fourier Transform Attenuated Total Reflection Spectroscopy (FTIR ATR). The experimental results are compared for both isoenzymes and the data are incorporated in a statistical attribution of secondary structure of the enzyme describing the ...

Differentiation of Chronic and Aggressive Periodontitis by FTIR Spectroscopy

Journal of Dental Research, 2016
Without longitudinal clinical data, it is difficult to differentiate some cases of chronic periodontitis (CP) and aggressive periodontitis (AgP). Furthermore, both forms of disease are exacerbated by tobacco use. Therefore, this cross-sectional study was planned, primarily, to determine the ability of Fourier-transform infrared (FTIR) spectroscopy to ...

Surface enhanced FTIR spectroscopy on membranes

Fresenius' Journal of Analytical Chemistry, 1998
The infrared absorption of molecules in the vicinity of small metal clusters is enhanced due to an electric field around the clusters. This phenomenon is known as surface enhanced IR absorption (SEIRA). The potential of SEIRA consists in the investigation of thin layers and of membranes.
