“…This method has been demonstrated useful for quantitative SERS detection of a variety of analytes, including aflatoxins, pesticides and herbal extracts, dispersed within a wide range of complex real-life samples, including paint, cooking oils and mouldy food. [149][150][151][152][153][154] However, colloidal deposition is a dynamic process, which leads to time-dependent SERS responses, and the product deposits are generally non- Please do not adjust margins Please do not adjust margins uniform, which results in irreproducible measurements. 155,156 Moreover, successful deposition of the enhancing colloid onto the sample requires knowledge of the positions of the separated sample spots on the TLC board.…”

The current review focusses on the importance of Raman spectroscopy in identification of pigments in ancient manuscripts and panel and canvas paintings. The major advantage of Raman spectroscopy is its non-destructive nature and its capacity of In situ analysis. The present paper discusses the pigments detected in different artworks, their chemical compositions and corresponding Raman bands. It highlights the fact that the establishment of the pigment palette of an artwork provides valuable information regarding degradation products and mechanisms which helps in conservation efforts. It also aids in understanding the authenticity of any specimen. Raman spectroscopy has transcended the boundary of cultural history and has been able to throw light on ancient trade routes, thus exhibiting its significance in the general historical study of a region. The article refers to publications during the period 1995-2022 in order to portray the versatility of the utilization of Raman spectroscopy in the stated arena.

“…However, this approach, employing modern DFPs, yields unsatisfactory results on the long-term. Since the formulation of the resin has been constantly modified, the present-day DFPs age in a different manner than the surrounding historical paint, and thus will eventually display a deviant appearance [5] In the past years, some attempts were made to enhance the understanding of the DFPs composition [9,10]. However, these studies focused on the characterization of the dye composition rather than on the resin and its additives and provided only limited information on the durability of the paint system as a whole.…”

started to incorporate Daylight Fluorescent Pigments (DFPs) in their artworks, the extent of the conservation problems that are associated with these pigments has increased progressively. Since their first appearance on the market, their composition has constantly been improved in terms of permanency. However, conservation practices on the artworks that are used in, are complicated by the fact that the composition of DFPs is proprietary and the information provided by the manufactures is limited. To be able to propose adequate conservation strategies for artworks containing DFPs, a thorough understanding of the DFPs composition must be acquired. In contrast with previous research that concentrated on identification of the coloring dye, this paper focuses on the characterization of the resin, used as the carrier for the dye. The proposed approach, involving ATR-FTIR, SPME-GC-MS and XRF analysis, provided additional insights on the organic and inorganic components of the resin. Using this approach, we investigated historical DFPs and new formulations, as well as different series from the main manufacturing companies (DayGlo, Swada, Radiant Color and Kremer) in order to obtain a full characterization of DFPs used by the artists along the years. First, the initial PCA-assisted ATR-FTIR spectroscopy allowed for an efficient classification of the main monomers in the resin polymer. Next, a further distinction was made by mass spectrometry and XRF which were optimized to allow a more specific classification of the resin and for detection of additives.In this paper we show the potential of SPME-GC-MS, never applied for the characterization of artistic materials, at present undervalued for heritage science purposes. We anticipate that this information will be highly relevant in the future stability studies and for defining (preventive) conservation strategies of fluorescent artworks.
