  Since a significant time ago, although time runs very fast,nanotechnology
transformed from one of the most promising scientific hopes in uncountable
human domains into a marvelous certainty. Innumerable scientific studies in
several areas of knowledge were made since nanoscale emergence, carrying their
contribution to the nanoscience development, leading to a great development of
technical and scientific knowledge but also raising numerous problems in the
ethical field. In this work, nanotechnology is discussed both in terms of
ethics and in terms of borders that nanotechnology applications must satisfy
and concluding notes are presented, highlighting the results of the analysis.
Significant considerations are made on the close connection between ethics and
the nanotechnology and the effects over the society and values.
