FTIR spectroscopic imaging allows the visualization of the distribution of chemical components in cells. However, obtaining images of living cells is difficult because of the strong absorption of water in the mid-infrared region. The use of attenuated total reflection (ATR) FTIR spectroscopic imaging provides a possibility to study tissues or live cells in an aqueous environment.[1] This approa...

A new Fourier transform infrared (FTIR) spectroscopic method based on single-bounce attenuated total reflectance (SB-ATR) spectroscopy was developed for the analysis of distilled liquors and wines. For distilled liquors, a partial least-squares (PLS) calibration was developed for alcohol determination based on the SB-ATR/FTIR spectra of mixtures of ethanol and distilled water. An independent se...

The utilization of Attenuated Total Reflectance – Fourier Transform Infrared (ATR-FTIR) spectroscopy for the characterization of pressure sensitive products is well established. Some recent advances in sensor technology have opened new application areas of ATR-FTIR spectrometry. One of them is monitoring of chemical reactions, which are of interest for pressure sensitive adhesive production. In...

Two spectroscopic techniques, attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) and Raman microscopy (RM), were used to characterize transport of chlorhexidine digluconate (CHG) in Candida albicans (CA) biofilms. Different (volumetric) regions of the biofilm are sampled by these two vibrational spectroscopies making them complementary techniques. Simple mathematical...

this study proposes a method employing thermogravimetric analysis (tg) to predict pollutionlevels by heavy metals (cr, cu, ni, zn, pb, cd and hg) in port sediments close to urban and industrial sitesfrom bay of cádiz. for this purpose, the thermogravimetric results of 14 sediment samples were recorded andshowed two characteristic ranges of temperatures (w1 as weight loss, %: 200-650°c) vs. (w2 ...

Background: The recent development of attenuated total internal reflectionFourier transform infrared (ATR-FTIR) spectroscopy has provided a new avenue for distinguishing cancerous tissue from normal one. The focus of this investigation is to develop a novel spectral discriminant method for thyroid malignant and benign samples, intraoperatively. Methods: A total of 112 cases of human thyroid tis...
