“…The Brécy Tondo, supposedly an artwork by Raphael, was analysed by Edwards and Benoy, [269] and a complete investigation on the technique of El Greco was reported by Daniilia et al [270] Other artworks examined include a 16th century painting Portrait of a Youth (Lau et al [271] ), a 13th century panel painting (Van der Werf et al [272] ) and South-Asian Shaman paintings (Vandenabeele et al [273] ). The Raman analyses helped to identify bassanite and anhydrite as degradation products in 16th century Portuguese oil paintings (Benquerenca et al [274] ), and Egyptian blue in a painting by Giovanni Battista Benvenuto from 1524 (Bredal-Jørgensen et al [275] ).…”

Minerals, as raw structural materials or pigments, play a fundamental role in archaeometry, for the understanding of nature, structure and status of an artefact or object of interest for cultural heritage. A detailed knowledge of the mineral phases is crucial to solve archaeological problems: Raman spectroscopy is a powerful investigation technique and has been applied extensively in the last 30 years on mineral identification and on pigment degradation. Here we report an updated review, covering the last decade, of the applications of Raman techniques to issues in which raw minerals, including mineral pigments, are involved. Particular attention is devoted to cases where the Raman analysis of minerals is deeper than a simple identification of the phases present in an archaeological or artistic object.

“…Fortunately, Egyptian blue (EB, CaCuSi 4 O 10 ), the oldest known synthetic pigment used in various ancient artifacts (e.g., paintings, wall paintings, tombs, mummies, coffins, etc. ), [ 29 ] is a Ca, Cu, and Si elements‐containing compound which shows the synergistic effects on prompted osteogenesis. [ 30 ] Besides, EB is also inexpensive and non‐toxic.…”

Ultrathin 2D Inorganic Ancient Pigment Decorated 3D‐Printing Scaffold Enables Photonic Hyperthermia of Osteosarcoma in NIR‐II Biowindow and Concurrently Augments Bone Regeneration

Osteosarcoma (OS) is the primary malignant bone tumor. Despite therapeutic strategies including surgery, chemotherapy, and radiotherapy have been introduced into the war of fighting OS, the 5-year survival rate for patients still remains unchangeable for decades. Besides, the critical bone defects after surgery, drug-resistance and side effects also attenuate the therapeutic effects and predict poor prognosis. Recently, photothermal therapy (PTT) has attracted extensive attention featuring minimal invasiveness and high spatial-temporal precision characteristics. Herein, an ultrathin 2D inorganic ancient pigment Egyptian blue decorated 3D-printing scaffold (CaPCu) with profound PTT efficacy at the second near-infrared (NIR-II) biowindow against OS and enhanced osteogenesis performance is successfully constructed. Importantly, this work uncovers the underlying biological mechanisms that genes associated with cell death, proliferation, and bone development are regulated by CaPCu-scaffold-based therapy. This work not only elucidates the fascinating clinical translation prospects of CaPCu-scaffold-based PTT against OS in NIR-II biowindow, but also demonstrates the potential mechanisms and offers a novel strategy to develop the next-generation, multifunctional tissue-engineering biomaterials.

“…X‐ray fluorescence (XRF) analysis represents the most accurate and fastest method in the inorganic material analysis of the analytical methods used for non‐destructive determination of the elemental composition . In recent years, portable XRF spectrometers have been developed for the in situ elemental analysis; they increased the efficiency of the method. However, XRF is known to be useful only in the analysis of inorganic materials (pigments in paints), but organic components in mural paint (from binders, coating formulation) undergo physical and chemical modifications as well under the environment influence (light, oxygen, humidity) …”

An analytical protocol consisting of X-ray fluorescence spectroscopy, optical microscopy and Fourier transform infrared spectroscopy was used to study the origin and the nature of the materials (pigments, binders and coating preparation) of the Fundenii Doamnei church mural paint from Bucharest. The main interest of the present study consisted in the original votive paint from narthex, painted in 1757 in a secco technique.During analysis, an unexpected pigment in the votive paint could be detected by the combined analytical techniques: ultramarine blue. Along with this pigment, the presence of gypsum binder based on egg and flax seed oil could also be evidenced. These results demonstrated a secco execution technique of the votive paint and also the presence of a restoration treatment. Moreover, during the present study, the components of the preparation layer and the constitutive pigments from both 1699 and 1757 years mural paints have been analyzed. Hence, the following pigments could be identified: vermilion, azurite, cinnabar, lead white, ochre, natural umber and gold, by using the combination of the analytical techniques.The novelty of our results consists in detecting the composition of the materials used in this church painting (fresco and a secco) during these 254 years since its first restoration.The results of these investigations pointed to the suitability of the non-destructive and semi-destructive analytical techniques in the complex characterization of the paints realized in different techniques, at different periods.
