Nanomaterials are a fantastic source of innovation and are used in many industrial sectors. However, their use may be limited by a lack of accessibility, validation or harmonization of methods for characterizing their key physico-chemical properties, as required by current regulations (R-Nano, REACh).

To meet these challenges, the NanoMesureFrance association was created in September 2022 through a public-private partnership between LNE, FEBEA and France Chimie. This structure aims to boost confidence in nanomaterials by federating the French players concerned by these analytical issues. In this context, in 2024 NanoMesureFrance published a guide illustrating the difficulties encountered during dimensional analysis by electron microscopy (SEM, TEM) and atomic force microscopy (AFM) of particles, confirmatory methods carried by the European Commission’s laboratory (JRC) in response to the 2022 revision of its recommendation for the definition of nanomaterials.

This webinar will present the innovative approach thus developed by NanoMesureFrance, designed to enable various stakeholders (analytical experts, regulatory players) to identify and anticipate the difficulties encountered when implementing such microscopy techniques. The complexity classes identified on the basis of feedback from NanoMesureFrance members will be introduced and illustrated using typical microscopy images to explain, on the basis of concrete examples, the difficulties most commonly encountered when analyzing materials made up of particles that may have sizes in the nanoscale. An analysis of the limitations inherent in the use of SEM, TEM and AFM microscopy tools will be proposed for these classes of complexity, and avenues of reflection will be explored with a view to developing the most appropriate analytical strategy.
