“…The collected infrared spectra appear similar and, apart from the typical signals characterizing silk (e.g. signals at 3279 cm −1 of NH vibration, 1620 cm −1 and 1510 cm −1 of amide I and II respectively, 1441 cm −1 of CH 2 and CH 3 bending in alanine, 1227 cm −1 of amide III, 1065 cm −1 of CH 3 rocking) [19,23,43], no specific peaks related to other compounds (such as colourants, mordants, etc.) could be easily identified.…”

“…Infrared spectroscopy analyses were performed with a portable ALPHA II spectrometer (Bruker Optics) equipped with an Attenuated Total Reflection (ATR) modulus based on a single-bounce diamond ATR crystal. The spectra acquisition was performed over the range of 4000-400 cm −1 accumulating 128 scans at a spectral resolution of 4cm −1 [23]. An equivalent number of background scans were conducted before each measurement.…”

“…Two sets of samples were selected from the costume collection of the Museo Histórico Nacional of Chile [22]; these samples belong to a group of textiles exhibiting worrying levels of deterioration. The first group includes light color weighted silk samples highly friable; its degradation has continued over time despite being stored under controlled conditions.…”

Background: Natural and synthetic colouring products along with its associated supporting materials have been studied in several expressions of the Chilean cultural heritage using vibrational spectroscopy. These expressions include archaeological remains as well as works of art. Results: Among the materials studied so far we can count pigments found in archaeological sites from the north of Chile, in plaster (wall paintings) and in polychrome (beams), and dyes mainly related to added components on historic silk textiles. Identification of materials resulted to be relevant to know about Chilean culture through history. Conclusions: The vibrational knowledge obtained contributes to give solid data as a complement to the different information aspects collected by conservation professionals involved in the characterization and conservation procedures of cultural heritage and also it gives us the opportunity to share knowledge and to give value to objects that not always are of the public domain.

“…In particular, research aims to correlate the degradation of fibroin with the presence of dyes, fibers manufacturing techniques, pollutants, etc. 18–21 . Both Fourier Transform Infrared Spectroscopy (FTIR) and Raman have been extensively used to analyze proteins, thanks to the possibility of correlating spectral features with structural information 22–24 .…”

Silk artifacts constitute an invaluable heritage, and to preserve such patrimony it is necessary to correlate the degradation of silk fibroin with the presence of dyes, pollutants, manufacturing techniques, etc. Fourier Transform Infrared Spectroscopy with a Focal plane array detector (FPA FTIR) provides structural information at the micron scale. We characterized the distribution of secondary structures in silk fibers for a large set of South American historical textiles, coupling FTIR with multivariate statistical analysis to correlate the protein structure with the age of the samples and the presence of dyes. We found that the pressure applied during attenuated total reflectance (ATR) measurements might induce structural changes in the fibers, producing similar spectra for pristine and aged samples. Reflectance spectra were thus used for the rigorous characterization of secondary structures. Some correlation was highlighted between the age of the samples (spanning over five centuries) and specific changes in their secondary structure. A correlation was found between the color of the samples and structural alterations, in agreement with the chemical nature of the dyes. Overall, we demonstrated the efficacy of reflectance FPA µ-FTIR, combined with multivariate analysis, for the rigorous and non-invasive description of protein secondary structures on large sets of samples.
