“…The development of nanotechnology is currently an emerging field in the conservation of cultural heritage, consequently the FP7 NANOFORART project has arisen (nano-materials for the conservation and preservation of movable and immovable artworks) and as an example of its applications, there are reports of the use of zinc oxide nanoparticles to control fungal biofilms or nanosilver coated cotton fabrics application for antimicrobial textile finishing [96][97][98][99].…”

Biodeterioration is defined as the undesirable change in the properties of materials caused by the activity of biological agents. This process is complex and involves alterations in the physicochemical and mechanical properties by the action of organisms and depends on the microorganisms involved, type of substrate, and environmental conditions. The biodeterioration of cultural heritage is the physical or chemical damage caused by microorganisms on objects, monuments, or buildings that belong to the cultural heritage. Among the main materials that can be affected are: stone, metal, ceramic, polymers, and other materials. Among the main undesirable effects to these materials are: discoloration, dissolution, rupture, and efflorescence among others. Biofilms represent the usual form of growth of bacteria and consist of communities of microorganisms that grow attached to an inert surface or a living tissue, surrounded by an extracellular matrix that they themselves synthesize. The importance of biodeterioration by biofilms is mainly related to changes in pH values, ionic concentrations, oxide-reduction reactions in the biofilm thickness, and in the interface with the substrate and enzymatic degradation. This chapter presents evidence of the participation of biofilms and associated mechanisms in biodeterioration as well as the main prevention and control strategies.

“…However, recent advancements have led to the emergence of minimally invasive techniques that prioritize authenticity while effectively mitigating deterioration. Nanotechnology, for example, has opened new possibilities for the consolidation and protection of cultural heritage materials, offering enhanced durability without compromising aesthetic value [11][12][13][14][15][16].…”

Cultural heritage is a fundamental part of the society’s identity, and its conservation is of great relevance as it transcends time and memory. To minimize its deterioration, cultural heritage has traditionally undergone diverse preservation and maintenance treatments and the attention of researchers to develop new and innovative methods for state diagnosis and protection treatments has been increasing in the recent decades. Therefore, in this study, a literature review using a bibliometric analysis and LDA methodology was conducted to systematically map scientific research outputs on cultural heritage conservation and protection. Data was retrieved from the Scopus database and the annual publications, countries, most-cited publications, authors, institutions, and keywords have been comprehensively analyzed, leading to the detection of research trends. Findings show an increasing number of studies in this field in the last decades, particularly since 2010. Italy, home to the largest number of UNESCO heritage sites, is the most prolific country. Most of the studies are related to metal, paper and stone as substrate to be protected. Significant progress has been made in understanding the deterioration processes through precise diagnosis and the development of innovative treatments for protection. In this sense, latest trends have been detected such as the use of non-invasive techniques for diagnosis and the use of nanotechnology and nature-based treatments for the conservation treatments.

“…Eventually, researches have proved that the efficiency of nanomaterials and nanocomposite and their physical, chemical and mechanical properties are better than the traditional ones which have been widely used in stone consolidation for many decades [18]. Inorganic nanomaterials are highly compatible with the stone material so they are commonly used in conservation treatment [19,20] and thus improve the properties of stone, when are used as consolidants [21]. Many recent researches have shown the effectiveness of nanomaterials in carbonate stones consolidation such as calcium hydroxide, barium hydroxide, magnesium hydroxide, strontium hydroxide and hydroxyapatite [22,23].…”

This study aims to evaluate the effectiveness of nanohydroxyapatite as a consolidating material for limestone monuments when dispersed in the SILRES ® BS OH 100, compared to the polymer in individual form. The current study was applied to one of the stone artifacts displayed at the Obelisk Open Air Museum in El-Matareya, Cairo. Treated samples were subjected to accelerated aging by moisture, temperature and salts to evaluate the stability of the consolidants. Nanohydroxyapatite/ polymer nanocomposite was prepared using in situ emulsion polymerization system. TEM, SEM-EDX, PLM, XRD, colorimetric measurements, water contact angle, porosity, capillary water absorption measurements and compressive strength tests were used to evaluate the consolidants efficiency. The results of thin sections revealed that the studied limestone samples were very fine-grained (micrite) containing microfossils. XRD analysis proved that the archaeological limestone consists mainly of calcite with a small percentage of gypsum, while SEM examination showed the weakness and high porosity ratio of the archaeological limestone samples. However, SEM investigation proved that the samples treated with HAP/ polymer nanocomposite have a homogeneous coverage, and the consolidant was able to fill pores and provide good consolidation. Moreover, the physical and mechanical properties of studied limestone samples were significantly improved as a result of the use of HAP/ polymer nanocomposite after treatment and aging.
