Paper has been used as writing and drawing support for thousands of years. The conservation of paper artworks plays a fundamental role in the field of our cultural heritage. Moreover, restoration of paper artworks is difficult due to their inherent fragility, the presence of many components and their degradation state. Among the factors that may co...
Article
Paper manuscripts are among the most valuable historical artifacts, but they are also very fragile. Furthermore, they were often strengthened by gluing external materials (like wooden or cardboard lining paper) to the original piece. The glues induced structural transformations that accelerate the degradation processes of the artwork itself. In thi...
Article
The removal of old glue from paper artworks is of paramount importance for the preservation of its integrity during the restoration process. Wet cleaning is one of the traditional methods, although, it may cause damages on artworks. In this work, an advantageous alternative method, based on the use of a rigid hydrogel, for a simple and localized re...

In this work an outlook on the design and application, in the cultural heritage field, of new tools for diagnostic and cleaning use, based on biocompatible hydrogels and electrochemical sensors, is reported. The use of hydrogels is intriguing because it does not require liquid treatment that could induce damage on artworks, while electrochemical bi...

... Its manufacture follows a common recipe in Europe [24]; moreover, it does not present specificities in the degradation status (foxing, walkways, aged linings or glues from previous restorations) that require specific treatments (i.e. hydrogels with enzymes or surfactants [30,31]). For these reasons, we retain that this artwork is suitable to perform a study on the effect of cleaning hydrogel. ...

... The biosensor and the preparation of Gellan gel and its application on the paper surface have been already described. 3,34,38 Briefly, the flow sampling system is applied directly on the Gellan gel on the opposite side with respect to the paper surface and is constituted by a plate in Perspex with a serpentine with 12 channels. Through the serpentine, the buffer flows continuously (moved by a peristaltic pump MINIPLUS3Gilson, USA), lapping the gel applied on paper samples ( Figure S1). ...
... Gellan hydrogel-immobilized α-amylases have been originally developed for removing starch paste from ancient paper documents (Mazzuca et al. 2014). A gellan-immobilized bacterial α-amylase ( Fig. 9.4) has recently been used to clean a wool shroud, dating back to the Coptic period, from starch glue that had been used in the 1950s to temporary consolidate the textile (Ferrari et al. 2017). ...
... The most important property of gellan, which is at the origin of its widespread use, is its capability of forming thermo-reversible transparent gels by cooling aqueous solutions containing cations, even at low polymer concentrations. The gellan sol-gel transition is an exothermic process [12] that can occur in a range of temperature between 30 and 50 • C, depending on the specific Another appealing property of gellan is its suitability as innovative agent for wet cleaning treatments in the restoration of paper artworks [21]. In a recent work [22], it was also demonstrated that microgels based on gellan, i.e. micro-scale particles internally made by a gellan cross-linked network, offer several advantages for paper cleaning with respect to more established procedure based on wet cleaning or hydrogels systems. ...
