Microorganisms cause massive damage to cultural assets worthy of protection every year. Currently used methods for the antimicrobial treatment of cultural assets are mostly limited in their efficiency or use toxic biocides. An investigation is being carried out into new methods for creating antimicrobial surfaces and their applicability in the protection of cultural property.
Paintings, books, textiles, metal objects, wooden objects, pieces of furniture – almost all types of our cultural heritage worthy of protection are affected by microbial infestation. Microorganisms such as bacteria, fungi and molds cause massive damage to art and cultural assets and even attack building facades or stone monuments. Air pollution and surface erosion further promote microbial contamination. However, microbial infestation of cultural assets not only affects the objects concerned, but also poses considerable health risks for visitors and employees of museums and depots as well as restorers.
Although numerous biocidal substances have long been known and used to protect cultural objects against microbial infestation, their effectiveness is often limited. In addition, there are now massive toxicological concerns about some of the biocides traditionally used, so their use should be avoided wherever possible.
Taking into account the specifics of individual cultural assets, the requirements for a biocidal protective coating can generally be summarized as follows:
Very similar requirements are now placed on antimicrobial protective coatings designed to protect the surfaces of medical devices (for example implants, prostheses and medical instruments) against microbial contamination. Like cultural assets, medical devices that are used every day in clinics or doctors’ surgeries are at risk of bacterial or fungal infestation. Such infections associated with implants can cause life-threatening complications. For this reason, extensive research has been carried out in recent years, including by the authors themselves, to develop antimicrobial surfaces for medical devices.
Due to the comparability of the requirement profiles for antimicrobial protective coatings for cultural assets and medical devices, it makes sense to take a closer look at new technologies for antimicrobial surfaces developed in medical technology and to examine their transferability to the protection of cultural assets. Therefore, selected new methods for the creation of antimicrobial surfaces for medical technology, in particular on the basis of nano- or microscale functional layers, and their applicability in cultural property protection are to be investigated.
