La nascita delle nanobiotecnologie: I nuovi nanomateriali, i potenziali applicativi, gli effetti tossici e le implicazioni per la Sanità Pubblica [The birth of nanobiotechnologies: new nanomaterials, potential uses, toxic effects and implications for public health]

Nanotechnologies hold considerable promise of advances in many sectors especially the biomedical field, since the materials used are of the appropriate dimensions to interact with important biological matter such as proteins, DNA and viruses. In this field the use of nanotechnologies will probably be second in importance only to biotechnologies. However many characteristics of nanomaterials that make them so promising from a technological point of view may also lead to negative effects on the environment and human health. It is important therefore that the environmental and work-related exposure effects to these materials be evaluated. In this article the potential uses, toxic effects and public health implications of nanobiotechnologies are discussed.
