In the field of restoration of cultural heritage, it has been developed coatings containing nanoparticles having multifunctional features, to protect stone materials against environmental degrading agents. Detecting such nanoparticle concentration within the coating, can represent a challenging issue because its monitoring over time can provide insights about the treatment durability. This paper deals with a theoretical basis to develop an instrumental method to fulfil this requirement.

In restoration of cultural heritage field, it has been developed nanoparticles coatings having multifunctional features to protect stone artifacts against environmental degrading agents. The nanoparticles concentration detection within the coating can represent a challenging issue because its monitoring over time can provide insights about the treatment durability. The “sample” under consideration consists in marble coated by amorphous silica in which nanoparticles are dispersed.
