Uses of nanomaterials have been increasing exponentially because they are reported to be better, more effective, stronger, lighter, harder and safer. Their biological, chemical, and physical characteristics can vary as a function of their size, which enables them to produce designed benefits. For example, the smaller is less visible and the more beneficial in cosmetic and medical applications. But, these engineered tiny substances could be potentially hazardous, due to adverse pollution and human uptake in the workplaces or the environments. This year (i.e., 2007) about $11 billion will be spent on developing new applications for nanomaterials research. Unfortunately, less than a billion dollars will used to identify possible health and environmental safety risks. All EH&S aspects must be studied and designed objectively, fully investigated and reported factually. The authors are dedicated to assisting this initiative and to achieving full beneficial utilization of nanotechnology in a safe and responsible manner. We look forward to becoming valuable partners together with those who are working to develop full realization of the benefits of nanotechnology in a safe and responsible manner.
