Nanosciences and nanotechnologies are a field of blooming technological applications, developed or manufactured at the nanoscale (a billionth of a meter). At this scale, matter shows new and unexpected properties. These may significantly differ from one case to the other, which results in a great diversity of different industrial applications, and eventually in very heterogeneous end-user products. As a matter of fact, the generic dimension of nanotechnologies, understood as a platform or enabling technology, drives their diversity, and potentially affects almost every industrial sector.
