MACRAM\u00c9 highlights challenges posed by complex structures and transformations of AdMas and AdMas-enabled products for regulation and industry drawn on research on graphene-related materials, carbon nanotubes and poly(lactic-co-glycolic) acid in realistic use cases. MACRAM\u00c9 translates advances in characterisation, transformation and release assessment, and New Approach Methodologies into actionable recommendations and calls on regulators, funding bodies, researchers and industry to develop and validate fit-for-purpose test methods, standards and guidance with the aim to enable safe and sustainable deployment of AdMas for societal challenges.<\/jats:p>","DOI":"10.3389\/ftox.2026.1895021","type":"journal-article","created":{"date-parts":[[2026,9,1]],"date-time":"2026-09-01T05:35:08Z","timestamp":1788240908000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Towards test guidelines and standards for advanced materials: scientific insights and recommendations from the MACRAM\u00c9 project"],"prefix":"10.3389","volume":"8","author":[{"given":"Anna","family":"Pohl","sequence":"first","affiliation":[{"name":"AcumenIST SRL","place":["Etterbeek, Belgium"]},{"name":"Federal Institute for Occupational Safety and Health (BAuA)","place":["Berlin, Germany"]}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniel","family":"Haase","sequence":"additional","affiliation":[{"name":"Gesellschaft f\u00fcr Bioanalytik M\u00fcnster e.
