Several repositories and databases are already contributing to data availability in nanotechnology: 1. Nanomaterial Registry: A comprehensive database that provides detailed information on the characteristics of various nanomaterials. 2. EUON (European Union Observatory for Nanomaterials): A platform that offers information on the safety and regulatory aspects of nanomaterials. 3. nanoHUB: A resource for computational tools and educational materials related to nanotechnology. 4. NIST Nanomaterial Data Repository: A repository by the National Institute of Standards and Technology that provides data on nanomaterial properties.
