paintings, statues), books, monuments, and frescos. Some of these works of art are subjected to environmental stressors like air pollution and microbial activity.The problem is not only what causes the damage but also how repairs are done.Quite often, the experts in charge of restoration work - architects, restorers, renovators - conduct their work without previous scientific studies of the damaged monument.To solve these problems, new nanoparticle-based consolidants were developed. In this work, we focused our attention on potential risks posed by three commercially available nanoparticle-based consolidants: silica (Si O NPs showed a dose- and time-dependent damage in all considered models.Corrosion test on Epi Skin® revealed no viability reduction.
