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...

Abstract Nano-Fourier-transform infrared spectroscopy (nano-FTIR) combines with scanning probe microscopy (SPM) techniques and enables spectroscopic imaging of molecular electronic properties matter at nanometer spatial resolution. The can be used to derive chemical mappings, i.e. the distribution concentrations species contained in a given sample. However, due sequential principle underlying S...
