7. Conclusion

Nanosciences, nanotechnologies and nanomaterials make up an immense and abundant whole, of which the preceding few pages give a very incomplete overview, as it has been deliberately limited, for the most part, to the field of information and communication sciences and the scientific disciplines from which they derive: electronics, magnetism, optoelectronics, while including the field of molecular technologies, the difficulties of which have already been mentioned. It has also been said that, despite the imagination of researchers and technologists, we can hardly be sure of overcoming them. Indeed, we may well wonder about the limits of the needs that will exist in this field, even in the distant future, and whether, having started fifty years ago with computer calculation, this field will not find itself limited in its ultimate developments to this field alone.
