Nanotechnologies are an emerging and multidisciplinary field of research, which is re-cently knowing a growing interest because of the basic and applied scientific break-through. Despite a deep understanding of the nanoscience is far to be achieved, the de-bate about the impact of nano-objects in everyday life is gradually involving both the scientific community and civil society. Here we provide some arguments to reflect upon the so-called “nanoethics”. We will start with a brief introduction about the definition of nanotechnology and then the circularity that links the characterization techniques in comparison with the discovery of nanotechnology will be discussed. Conclusion remarks about the presence of nanotechnology in everyday life will be finally presented.
