Innovative apatitic materials with enhanced antimicrobial activity for building materials and cultural heritage conservation
Whether we are talking about hospitals, where the antimicrobial property of the building itself will be an aid against intra-hospital infections, a historic building belonging to the national / international heritage that needs consolidation and / or surface treatment or stone monuments that need only surface treatment, the solutions developed in this project will represent not only an alignment at the international scientific level, but also an important technical solution, which will contribute to the sustainability of the project after the implementation period.
The main goal of the project is the development of an innovative and versatile solution (consisting of hydroxyapatite derivatives), solution that could be applied either by incorporation into the building material (primary objective) or by surface spraying (secondary objective). From the project will emerge new solutions to an increasing problem, respectively the microbial loading of various buildings and stone.

The project proposes the use of metal-substituted hydroxyapatite as antimicrobial component for building materials. This solution will be viable for multiple applications related to its use for new buildings with special requirements related to microbiological loading (such as hospital buildings) and for consolidation of cultural heritage constructions; also the use of substituted hydroxyapatites for protection of stone artifacts against environmental factors (acidic rain) and biodeterioration through spraying on their surface will also be evaluated. The validation of the proposed technologies will be obtained via third-parties studies.
The previous obtained results allows the consortium to define daring targets, while the experience of the researchers involved ensures their fulfillment; in the same time, the potential of the solutions offered at the end of the project will ensure the future development of the project idea towards higher technology readiness levels.
