Deterioration of building materials driven by fracture evolution and corrosion, imposes huge economic burdens to Europe. Corrosion alone accounts for worldwide expenditure over 1 trillion US dollars, amounting to 3-4 % of the GDP of devel-oped countries. NanoHeal will focus on the development of strategies for self-healing of cements used in the construction industry and in biocompatible implants. Inspired by biomineralization in nature, we propose that the interfacing of organic compounds with minerals will bring a new paradigm to design cementitious materials. Healing in construction and biogenic materials can be achieved by controlled dissolution and growth at mineral interfaces under nanoconfinement. Building knowledge in this research area is therefore of utmost importance. Recent results show that organic molecules and membranes at mineral-fluid interfaces drastically modify nucleation and growth of the adjacent solid surfaces . Classical theories fail to predict these observations, highlighting the need for improved concepts, theories and models to design self-healing materials. Organic molecules are ubiquitous in limestone, chalk and biominerals. They are also used as admixtures in the cement industry. However, their role in construction materials is not well understood, while biomolecules are clearly of key im-portance in shaping biogenic minerals. We believe that learning the main lessons of how organic molecules interact with biogenic minerals will offer new routes to design stronger materials with the ability to heal themselves. This is the key scientific aim of NanoHeal, which will be achieved by combining unique experimental and computational modelling capa-bilities.
