Nano ?


Nano-objects (particles, fibers, plates, tubes,...) are entities with at least one dimension is smaller than 100 nanometers. These entities are the basis for the formation of nano-structured materials on the surface or in volume. They are passive or active as nanodevices. This website deals the risks associated with nanomaterials without covering the wider field of nanotechnologies.
Cartoons Episode 1


Two convergent and complementary approaches. Many scientists consider the zone is more precisely define by 1-100 nm.

In the "nano" zone, classical and quantum mechanics partially govern traditional disciplines (physics, chemistry and biology).

Nanotechnologies applied to various sectors such as Materials, Information or Health Technologies and concern designing, characterization, production and application of structures, devices and systems at the nanoscale. We can distinguish "top-down" approach (from micro towards nano”) from "bottom up" approach (from molecule towards “nano”).
