Research in the nanoparticle (NP) and nanotechnology field is growing at a breathtaking pace. The reason is simple: the unique properties of NP will allow the development of products with unprecedented characteristics and opportunities in every field of human activity, and with tremendous economic impacts. It is currently anticipated that the number of exposed Quebec workers, not only in manufacturing these products but also in using and processing them, will increase over the next few years. Several products are already available commercially and some Quebec companies now have large-scale NP production capacity. While technological research is already well.
