"Nanotechnology could have an enormous impact on medicine but, says Michael Helmus, the regulations that govern new drugs and medical devices need to be updated before nanomedicine can be commercialized. In recent years there has been increasing interest in the impact of engineered nanoparticles on human health and the environment. At the same time it has become clear that some of the most exciting opportunities presented by nanotechnology are in the field of nanomedicine."
