European Commission and NIA publish First Set of Results from the OECD Sponsorship Programme on the Safety of Manufactured Nanomaterials

The European Commission Joint Research Centre (JRC), supported by the Nanotechnology Industries Association (NIA) and its member company RAS Materials, has published the first report in a series on the NM-Series of Representative Manufactured Nanomaterials. Entitled 300 Silver - Characterisation, Stability, Homogeneity, the report marks the start to the publication of the first set of results obtained under the OECD WPMN Sponsorship Programme on the Safety Testing of Manufactured Nanomaterials.

The report provides a general introduction to the 'JRC Repository of NM-Series of Representative Manufactured Nanomaterials and the OECD Sponsorship Programme', including a description of the 'JRC repository of NM-Series of RMNs' and the 'NM-Series use at the OECD', before going on to present the results of detailed analyses of characterisation conducted on the specific nano-Silver NM-300 that was adopted as one of the Principal Manufactured Nanomaterials under the OECD Sponsorship Programme:

'The present report describes the characterisation of NM-300, a RMN nano-Silver dispersion containing nanoparticles (NPs) smaller than 20 nm, originating from a single batch of commercially manufactured nano-Silver, used for measurement and testing for hazard identification, risk and exposure assessment studies...The nano-Silver material was provided as a representative [of an] as-produced commercial nanomaterial and its NM-Series processed in the frame of the JRC programme on nanomaterials. It was studied by a number of international laboratories including the JRC Institute for Environment and Sustainability (IES) analytical laboratory'.

'The work of the OECD and the JRC NM-Series and Reference Nanomaterials Repository is important not only for the nano-Silver industries; it answers stakeholder questions in a globally coordinated fashion, providing reliable performance standards for the nanotechnology industries. The material provided by us to this programme is produced and distributed worldwide by RAS Materials GmbH for application as a new-generation antimicrobial in all types of polymers processed by the medical and consumer industry'.

According to the introduction, 'the properties of NM-300 studied and described in this report demonstrate its relevance for use in measurement and testing studies, such as for hazard identification, related to the safety of nanomaterials. The studies were performed in close collaboration with the Fraunhofer Institute for Molecular and Applied Ecology (Fh-IME), German Institute of Energy and Environmental Technology e.V. (IUTA), the Swiss Federal Laboratories for Materials Science and Technology (EMPA), RAS Materials GmbH, Germany, and the Veterinary and Agrochemical Research Centre (VAR) in Belgium'.
