Nanotechnology: legal and ethical issues

Nanotechnology is a very vast field which includes a range of technologies at the nano scale, such as pharmaceuticals, biotechnology, genomics, neuroscience, robotics and information technologies. Nanotechnology is the latest technological innovation in global debates on risk regulation and international cooperation. Regulatory bodies have started dealing with the potential risks posed by nanoparticles. Since 2004 the UE has been developing a regulatory policy to tighten control and to improve regulatory adequacy and knowledge of nanotechnology risks. Currently, specific provisions on nanomaterials have been introduced for biocides, cosmetics, food additives, food labelling and materials in contact with foodstuff. The statement that nanotechnologies do inevitably imply ethical questions. The main problems are public trust, potential risks, issues of environmental impact, transparency of information, responsible nanosciences and nanotechnologies research. The aim of this article is to analysis the main problems regulating nanotechnology and some aspects of ethics.
