“…In micro-FTIR techniques, an infra-red spectrometer is linked to a microscope, so the sampling areas of interest can be visually identified in order to obtain the spectral data. Since all the intensities are relative, no direct quantitative comparison can be performed between intensities of different bands [57] .…”

In this study, we investigated the microbial community (bacteria and fungi) colonising an oil painting on canvas, which showed visible signs of biodeterioration. A combined strategy, comprising culture-dependent and -independent techniques, was selected. The results derived from the two techniques were disparate. Most of the isolated bacterial strains belonged to related species of the phylum Firmicutes, as Bacillus sp. and Paenisporosarcina sp., whereas the majority of the non-cultivable members of the bacterial community were shown to be related to species of the phylum Proteobacteria, as Stenotrophomonas sp. Fungal communities also showed discrepancies: the isolated fungal strains belonged to different genera of the order Eurotiales, as Penicillium and Eurotium, and the non-cultivable belonged to species of the order Pleosporales and Saccharomycetales. The cultivable microorganisms, which exhibited enzymatic activities related to the deterioration processes, were selected to evaluate their biodeteriorative potential on canvas paintings; namely Arthrobacter sp. as the representative bacterium and Penicillium sp. as the representative fungus. With this aim, a sample taken from the painting studied in this work was examined to determine the stratigraphic sequence of its cross-section. From this information, “mock paintings,” simulating the structure of the original painting, were prepared, inoculated with the selected bacterial and fungal strains, and subsequently examined by micro-Fourier Transform Infrared spectroscopy, in order to determine their potential susceptibility to microbial degradation. The FTIR-spectra revealed that neither Arthrobacter sp. nor Penicillium sp. alone, were able to induce chemical changes on the various materials used to prepare “mock paintings.” Only when inoculated together, could a synergistic effect on the FTIR-spectra be observed, in the form of a variation in band position on the spectrum.

“…FTIR was actually reported useful in studying and documenting the effects of degradation and ageing on textile fibres at a molecular level, when applied to historic textiles successfully showing different stages of degradation of cellulosic fibres [10], and to biodegraded historic textiles, where it was able to detect structural changes in the cellulosic fibres caused by fungi [11,12] and qualitative analysis of materials present in cross-sections of the fibres when combined with a synchrotron radiation source (SR) [13]. In fact, the ability of FTIR in detecting changes induced by degradation due to ageing in regions of the produced spectra of cellulosic fibres proposed it as an alternative technique to dating cellulosic textiles [14,15], with promising results, although quite sensitive to the environmental factors and the effects of chemical processing (like bleaching), the fibres might have undergone [16].…”

“…Moreover, the applications of ATR reviewed took place mainly on historic rather than excavated textiles, the condition of the former being markedly better [e.g. 10,12,13], and when excavated textiles were reported, these were from Egypt [e.g. 14], a place that has thankfully provided us with an abundance of important finds in remarkably good condition.…”

The application of FTIR microspectroscopy in a non-invasive and non-destructive way to the study and conservation of mineralised excavated textiles

The potential of Fourier Transform Infrared (FTIR) microspectroscopy, to inform the study and conservation of mineralised excavated textiles is discussed, highlighted by two case studies of 5th c. BCE finds. In both cases the textiles were funerary from pyre burials, used to wrap the remains of the incinerated bones of the deceased, and placed inside copper alloy urns, to be buried. FTIR spectra of the textile fibres were acquired by an FTIR microscope in reflectance mode. In regard to the two case studies, this was a non-invasive and non-destructive method, since it did not involve removal of material for sampling, as both finds were in a fragmentary condition, it did not apply any pressure, nor did it require pressing of the minute fragments used as samples. Past fibre analyses in case study A reported cultivated and wild silk, which had been used as evidence of the presence of silk in Classical Greece, while more recent studies, controversially pointed to either cellulosic or wool fibres. The unlimited application of FTIR microspectroscopy in reflectance mode due to its non-invasive/destructive nature, enhanced fibre identification but most importantly led to further analyses of specific fragments that revealed the find was suffering from active biodeterioration, subsequently treated. Case study B, where the textiles had been preserved folded, was a particularly unique find from its period, since one of the textiles present was bearing evidence of embroidery. Similarly, the extended application of FTIR microspectroscopy indicated good preservation of the organic matter within the fibres, informing thus the conservation decision-making process, which involved partial unfolding of the textiles, an action that revealed an additional decoration pattern, and minute fragments of the embroidery thread preserved.

“…The study combines the techniques of SE and synchrotron‐source attenuated total reflection‐Fourier transform infrared (ATR‐FTIR) spectroscopy. By using synchrotron radiation, the provided radiation is 100–1,000 times brighter than a conventional globar source 40 . A powerful source can provide a good signal‐to‐noise ratio, which allows a very small amount of sample to be analyzed 40–42 …”

Poly(N‐isopropylacrylamide‐co‐acrylamide) (PNIAM‐co‐AM) grafted onto tissue culture polystyrene surfaces (TCPSs) with different thicknesses and grafting densities were prepared by varying the spin‐coating speed and UV irradiation time for use in cell sheet engineering. The thickness of the PNIAM grafted surface, less than 30 nm, was believed to influence protein adhesion and cell attachment. However, methods for determining the thicknesses of a thin surface (nanometer scale) are still a challenge. In this study, a model was developed to relate the thickness of the PNIAM‐co‐AM film to its grafting density. Spectroscopic ellipsometry (SE) and attenuated total reflection‐Fourier transform infrared spectroscopy (ATR‐FTIR) with synchrotron radiation were used to quantify the thickness and the grafting density, respectively. The amount of the grafted copolymer was determined from quantitative ATR‐FTIR by relating the signals at wavenumber 1,654 to 1,600 cm−1 (A1,654/A1,600) to the known grafting density. A combination of SE and ATR‐FTIR was used to construct a linear model (h = 6.29σ + 2.24), to obtain the grafting density (σ) from the film thickness (h) with R2 = 0.93. To validate the model, random samples were prepared with different thicknesses and grafting densities. The linear model was used to predict the grafting density, which was nearly equal to the measured values.
