FTIR spectroscopy has long been used for the analysis of art and historical objects in support of efforts to conserve, restore and validate authenticity of these rare objects. The value of the technique for this application lies in its inherent sensitivity, specificity and non-destructive capabilities. Typical applications include analysis of paint pigments and binders, lacquers and finishes. F...

Monte Carlo (MC) Simulations, Differential Scanning Calorimetry (DSC) and Fourier Transform InfraRed (FTIR) spectroscopy were used to study the melting behavior of single lipid components in two-component membranes of 1,2Dimyristoyl-D54-sn-Glycero-3-Phosphocholine (DMPC-d54) and 1,2-Distearoyl-sn-Glycero-3-Phosphocholine (DSPC). Microscopic information on the temperature dependent melting of th...

The aim of this study was to compare polymerization lamps of various technologies (halogen, high performance halogen, xenon, i.e. plasma arc, as well as diode lamps) to determine the degree of polymerization of composite probes using Fourier-transform infrared (FTIR) spectroscopy. To observe the light-induced curing reaction under a bracket, an attenuated total reflection (ATR)-FTIR was used. T...

Wehave been developing techniques to apply propagating surface plasmon polariton (SPP) resonances to the spectroscopic study of individual, subwavelength-sized particles. SPPs, mixed states of light and conducting electrons at the surface of a patterned metal surface, are part of, that is, mediate, the extraordinary transmission/reflection resonances of patterned metal meshes. A fair body of wo...

Infrared spectroscopy is one of the oldest and well established experimental techniques for the analysis of secondary structure of polypeptides and proteins. It is convenient, non-destructive, requires less sample preparation, and can be used under a wide variety of conditions. This review introduces the recent developments in Fourier transform infrared (FTIR) spectroscopy technique and its app...

Fourier transform infrared (FTIR) microscopic imaging uses a combination of an FTIR spectrometer with a microscope and Focal Plane Array (FPA) detector. The method has been recognized as a powerful and versatile imaging tool in many disciplines, ranging from biomedical research through to materials science, art conservation and forensics. The Field Of View (FOV) depends on both the magnifi cati...

The evolution of papermaking from XII century, in Europe, was characterized by continuous changes of fibrous and non-fibrous materials as cellulose, wood pulp, sizing agents, fillers and coatings. In this study, the composition of many ancient paper documents is analysed by means of non-destructive Fourier Transform Infrared Spectroscopy (FTIR) in order to identify the main components of paper ...

In this report, we present a novel spectroscopic method of follow-up during chemotherapy treatment for B- and T-cell childhood leukemia patients. We isolated peripheral lymphocytes from blood drawn from patients before and after the chemotherapy and collected Microscopic FTIR (FTIR-MC) spectra of the isolated lymphocytes. Our results showed that nucleic acids content decreased in both types of ...

Ground-based Fourier Transform Infra-Red (FTIR) measurements are an important component of the global atmospheric monitoring system. Their essential role in validating satellite measurements requires a precise documentation of their quality. Here we present an extensive quality documentation of ground-based FTIR O3 profiles. This is done in the form of theoretical and empirical error estimation...
