Abstract

In the context of the conservation of cultural heritage, a problem to be solved is the biological degradation of monuments. The biocidal agents used for cleaning biodegraded surfaces are few and must have adequate requirements. One of the main challenges is the development of eco-friendly products for the conservation and restoration of cultural heritage. Deep Eutectic Solvents (DESs) are a class of green solvents, beneficial and safe that could be used as biocides in cleaning and preserving cultural heritage. In this contribution, five different DES were applied for the first time as biocides on a mosaic in the Archaeological Park of Ostia Antica (Rome) and their biocidal action was evaluated by luminescence, bioluminescence and spectrocolorimetry analyses. The first results obtained from this study are very promising for the use of DESs as a new green strategy for the treatment of biodegraded surfaces in the field of cultural heritage.
