" Nanotechnology" expands across research domains, applications and products and remains a field with neither a single scientific definition nor a formal regulatory or statutory definition. This definitional question is an international challenge, with most developed countries actively contemplating whether this expansive technology requires additional regulation. As part of the National Nanotechnology Initiative (NNI) in the United States, 26 federal agencies, including the Food and Drug Administration (FDA), contributed to the development of a description for nanotechnology as:" 1) Research and technology development at the atomic, molecular or macromolecular levels, in the length scale of approximately 1-100 nanometer range; 2) creating and using structures, devices and systems that have novel properties and functions because of their small and/or intermediate size; and 3) ability to control or manipulate at the …
