History of nanoscience and nanotechnology, properties of materials at the nano scale, definitions and regulations. Description of the main families of nanomaterials (NP, porous materials, 2D-3D networks, surfaces, composites, etc.), overview of the fields of application of nanomaterials (NANOWERK). Characterisation techniques (structures, composition, properties), top-down / bottom-up chemical / physical nanofabrication techniques (ablation, nanofabrication, VLS, colloidal chemistry, deposition techniques, lectrochemistry). Examples of materials and applications (optics, electronics, chemistry, mechanics). Implications of nanomaterials.
