The European Commissions Joint Research Centre (JRC) has published a new report reviewing the methods used for measuring nanoparticle size, in support of the European Commission’s recommendation on a common definition of the term “nanomaterial” for regulatory purposes.

This blog has always made clear that in order to enforce this definition in a regulatory context, appropriate validated measurement methods are required. The report also considers nanoparticle reference materials (see blog post of 17 September).

The report covers ensemble methods (e.g. dynamic light scattering and small-angle X-ray scattering), used for measuring large numbers of particles simultaneously, counting methods (e.g. particle tracking analysis or electron microscopy) and fractionation methods (e.g. centrifugal liquid sedimentation and field flow fractionation), so is therefore very comprehensive in considering all the measurement issues relevant to measuring size and numbers of nanoparticles in support of the Commission definition.
