General objective


The main objective of the project is to provide practical solutions based on new antifungal recipes to reduce the impact of heritage biodegradation, recipes based on the use of soft nanomaterials, applicable in the form of xerogels or spray.

Exploiting the synergistic action of the materials used and establishing an optimal ratio between them is an element of scientific / technical novelty of the project, as well as the use of similar but individualized recipes for several types of artifacts - ceramic artifacts and paper artifacts.

Specific objectives


  • Optimizing the synthesis of nanomaterials by controlling the properties and dimensions for a better antifungal effect and characterization of materials;
  • Establishing an optimal ratio of materials in the proposed innovative recipes and exploiting the synergistic action;
  • Establishing the application method according to the support material of the artifact;
  • Study of the interaction between the proposed recipes and the support materials (archaeometry studies before and after treatment);
