Several international organizations and national bodies are involved in harmonization efforts, including:
ISO (International Organization for Standardization): Develops global standards, including those for nanotechnology. OECD (Organisation for Economic Co-operation and Development): Focuses on the safety of manufactured nanomaterials. ICNTS (International Council on Nanotechnology Standards): Works on global nanotechnology standards. National Institutes such as NIST (National Institute of Standards and Technology) in the USA and NPL (National Physical Laboratory) in the UK.
