Registrations submitted to the nanoregistry in 2017 and 2018 have been scientifically assessed by Sciensano.
This study aimed at analyzing the quality of the data submitted and their compliance with the registration form, i.e. the correct filling in of the " mandatory " fields that allow a comprehensive physicochemical characterization of the nanoparticle substance.
An evaluation as to whether the measurement method mentioned is appropriate has also been carried out.
Finally, a qualitative analysis of the database and recommendations were provided to the managers of the nanoregistry.
