The presented project aims to provide practical solutions for ceramic and paper artifacts, based on new antifungal recipes, in order to reduce the impact of biodegradation of cultural heritage artifacts. The developed recipes, specific for each type of support material (ceramic and paper), will be based on the use of soft nanomaterials, applicable in the form of xerogels or spraying. The recipes will take into consideration the interaction between the developed materials and the support materials. Keywords: Nanomaterials, Ceramic Artifacts, Paper Artifacts, Antimicrobial Recipes. 1 Introduction The cultural heritage and architectural monuments are exposed to environmental pol- lutants, climatic factors (temperature, humidity, rain and other precipitations, sun ex- posure) and chemical treatments (biocides, surfactants and hydrophobic compounds) that facilitate microbial growth, resulting in physical, chemical, but also aesthetic ef- fects. An adequate assessment of biodegradation and material disintegration requires a combination of microbiological, surface and material characterization techniques. Several research papers, including those published by our group, presents the appli- cation of alternative methods in the area of restoration/conservation of cultural heritage artifacts, including the use of natural extracts (Barresi et al., 2017; Fierascu, R.C., et
