----------
The aim of this contribution is to outline and define some ethical implications concerning biomedical applications of nanotechnologies. Nanotechnology, expression of the human ability to manipulate matter on a molecular and atomic scale, provide an instrument able to change scientific research and medicine in a radical way. Debate at all levels have pointed out the common difficulty to give a clear and univocal definition of nanotechnologies, due to the convergence of technologies there involved. Although these technologies have already been implemented in electronics or computer science, the most useful ones are foreseen to be in new approaches for research purposes and medicine, providing diagnosis and drug delivery with no invasive methods involved. These technology, in fact, look like therapy but they also represent unique prevention tools. The very same characteristics that make nanomaterial useful in medicine, suggest some precaution: o one hand, thanks to their small size (atomic dimension) nanoparticles can enter cells in the organisms, avoiding natural defenses and move to organs and tissues allowing a target distribution of drugs. On the other hand, these technologies can turn to be harmful to humans (interaction between nanoparticles and the biological human system, high surface- to-mass relation, mobility). Because we are dealing with a rapidly developing technology, where most of the effects are still hard to foresee, potential risks must be considered for both current and future applications. So far, outlining ethical issues means understanding the impact of these technologies on human health.
