Nano definition raises as many questions as it answers
Abstract:
The Institute of Food Science and Technology (IFST) has welcomed moves by the European Commission (EC) to develop a definition of nanomaterials for regulatory purposes, but raised some concerns about the draft definition currently out for consultation.
Responding to the EC's consultation document containing a definition of ‘particulate nanomaterials' focusing on materials in the 1-100 nanometre range, the IFST said the size at which the properties of a material could abruptly change varied widely according to the material and the properties in question.
"There is thus concern over the selection of the single upper size boundary. For biological materials the measurement of size and size distribution can also be dependent on the sample preparation method and the method used to size the samples."
