Paper-based artworks are among the most valuable assets for transmission of knowledge. Historical paper is composed of different polysaccharides (e.g. cellulose), binders, and glues. During aging all of these components undergo several degradation processes, as a result of external and intrinsic causes, and these can compromise the state of conservation of the document. In this work, application of a new biotechnological strategy for paper artefact preservation is reported. By making use of innovative and non-invasive materials, for example appropriate hydrogels, in combination with selective electrochemical biosensors, it is possible to simultaneously verify the degradation condition of the paper artwork and then to efficiently clean it, while monitoring the process of removal of both pollution and degradation products. In this paper, we focus on specific examples in which such techniques have been applied to paper artworks and that illustrate the advantages and potential of this biotechnology compared with the traditional paper-cleaning methods currently in use.
纸质艺术品是知识传播的最有价值的资产之一。历史纸张由不同的多糖(如纤维素)、粘合剂和胶水组成。在老化过程中,所有这些成分都会由于外部和内在原因经历几种降解过程,这可能会影响文件的保存状态。在这项工作中,报告了一种新的生物技术在纸质艺术品保护中的应用。通过利用创新和非侵入性的材料,例如适当的水凝胶,并结合选择性电化学生物传感器,有可能同时验证纸质艺术品的降解情况,然后有效地清洁它,同时监测去除污染和降解产物的过程。在本文中,我们重点介绍了这些技术在纸质艺术品上应用的具体例子,说明了与目前使用的传统纸质清洁方法相比,这种生物技术的优势和潜力。
