The Boom in Nanomaterials for Built Heritage Conservation: Why Does Size Matter? Otero Hermo, Jorge Borsoi, Giovanni Monasterio Guillot, Luis Nanolime Nanomaterials Cultural heritage conservation Nanoscience Nanotechnology There is no doubt that nanotechnology and nanoscience open new doors to new applica- tions and products that can potentially revolutionize the practice field and how we conserve built heritage materials. However, we are living at the beginning of this era and the potential benefits of nanotechnology to specific conservation practice needs are not always fully understood. This opinion/review paper aims to present reflections and answer a question that we are often asked when working directly with stone field conservators: why should we use a nanomaterial instead of a conventional product? Why does size matter? To answer this question, we revise the basic concepts of nanoscience with implications for the built heritage conservation field. 2023-05-30T10:12:25Z 2023-05-30T10:12:25Z 2023-04-21 journal article Otero, J.; Borsoi, G.; Monasterio-Guillot, L.
