USE OF THE FOURIER TRANSFORM INFRARED SPECTROSCOPY IN CHARACTERIZATION OF SPECIFIC SAMPLES

Abstract

Spectrometria in infrarosu cu transformata Fourier a devenit una dintre principalele tehnici utilizate atunci când este abordata analiza unor probe cu o specificitate deosebita, care necesita o analiza nedistructiva. Astfel de situaţii apar atunci când trebuie sa fie analizate probe arheologice/de patrimoniu, ca si atunci când trebuie caracterizate biomateriale specifice. In acest articol prezentam unele rezultate experimentale care, prin argumentele aduse, justifica importanţa utilizarii acestei tehnici in elucidarea unor aspecte critice privind caracteristicile structurale ale acestor tipuri de probe. Studiile noastre au fost efectuate pe probe de chihlimbar (arheologic si geologic) si pe sisteme biomimetice obţinute prin imobilizare de biomolecule (enzime) pe nanoparticule funcţionalizate. The Fourier Transform Infrared Spectrometry analysis became one of the main used techniques when peculiar topics are addressed, mainly when nondestructive analysis is needed. In this respect, according to our opinion, interesting analytical issues are raised, for example, when historic (archaeological)/patrimony materials have to be analyzed or when the analysis of highly- specific biomaterials have to be performed. In our paper data are supporting both potential specific application of Fourier Transform Infrared Spectrometry on provided samples. the studies have been performed on amber (archaeological and geological) and biomimetic systems obtained by immobilization of active biomolecules (enzymes) on functionalized nanoparticles.
