The aim should be to identify a general class of materials for attention \u2014 whether they are benign or hazardous.\u201d While conceding Maynard\u2019s point that nanomaterials are heterogeneous is justified, he argues that they all have structures on the nanoscale, which modify their other properties. Size is then, says Stamm, the most appropriate parameter on which to base a broad definition, adding, \u201cA definition is required for labelling purposes, and would assist industry and regulators in identifying where specific safety assessments might be necessary.
