title: [Nanoparticles: structures, utilizations and health impacts].
abstract: Nanotechnology is a scientific domain with a full expansion. Nanomaterials have a big variety of applications in many technological domains. The diffusion, the persistence in atmosphere and the health impacts of nanoparticles are totally different by the bigger particles for the same chemical composition. Studies made, found, cutaneous, pulmonary, cardiovascular and carcinogen toxicities. Properties of nanotubes show that their toxicity may be close to asbestos. Many studies concerning health impacts and environment effects are in course, and the results will be available in a few years. Suspected health impacts on humans and animals justify, in the spirit of precaution, to make all that's possible to reduce the exposure and to protect the health of the exposed people.
