As a follow-up of the first NanoDefine industry-focused workshop in 2016, a second one was arranged in the final year of the project on 24 October at DECHEMA Frankfurt, together with the German VCI. Main purpose of this event was the practical demonstration of key measurement techniques developed to industrial end-users, regulatory bodies, enforcement labs and to the wider community. This final NanoDefine dissemination event has attracted about 80 representatives from all over Europe (including one participant from Japan!) and from a wide variety of stakeholders, including material manufacturers, especially from the paint, pigment and fillers industry.

The workshop started with a short introduction into background, goals, challenges and main outcome of the NanoDefine project. This was followed by a presentation on experiences and needs of industries to meet the analytical challenges associated with the regulatory implementation of the EC Nano-definition. Different presentations highlighted the main outcome and products generated in the individual work packages to address the question, “how to measure and classify real-world materials according to the EC recommendation”.

There was an intense discussion on project achievements in terms of the performance of new protocols and validated SOPs developed, of novel instruments and software established, but also in relation to the strength and weakness of the newly developed methodology to tackle complex and real-world samples. Main discussion points addressed the applicability of the NanoDefine measurement strategy to accurately and truly determine and identify nanomaterials in a wide range of real industrial samples, the potential of the NanoDefine 2-tiered approach applying rapid and cost-efficient screening and more in-depth confirmatory methods to classify substances and products, and the challenge of validating and standardizing the tools developed for reliable nanoparticle analysis. Finally, an introduction in the NanoDefine decision support flow schem e with the “NanoDefiner” e-Tool” was given that provides guidance to practitioners in method selection and material grouping (nano/non-nano). An overview on case studies performed to prove the applicability of the methods to complex industrial samples wrapped up the morning session.

Main focus in the afternoon was the practical hands-on demonstration of the various measurement techniques and instruments developed by NanoDefine, including spICP-MS, PTA, the autoEM-toolbox and miniTEM, HRMS and an electrospray deposition prototype for proper EM sample preparation.

Final highlight was the demonstration of the NanoDefiner e-Tool to the whole auditorium and its capability to find out if a material or product is or consists nano, or not.
