ABSTRACT
Although nano-based research and development has been around long enough to no longer be “new”—indeed the claim is made that carbon nanotubes were present in the swords of crusaders in A.D. 500-research concerning real or perceived modern-day risks remains in the early stages. As nanoscale materials can exhibit different chemical or physical properties as compared to larger-scale counterparts, important questions have emerged about the impact on our environment, health, and safety, prompting numerous regulatory agencies to devote significant resources to the study of nanoscience, with few concrete regulations yet to emerge.
