Nanomaterials: synthetic aspects and interaction with biosystems

Abstract
The intense development of nanotechnologies is strongly related to nanomaterials. An important aspect of this development is related to the synthetic methods used in its production. For this, several approaches are used that range from high temperature synthesis, soft-chemistry, sol-gel method, template synthesis to CVD. Equally important is the complete characterization of nanomaterials using often sophisticated physicochemical techniques. In this lecture we will show some methods developed in our laboratory to obtain materials with different morphologies: nanotubes, nano-wires, nanospheres and lamellar materials (2D). By other hand, the possibility of applying these different materials is strongly dependent on their nanotoxicity against man and the environment. In this context, examples will be presented and discussed from the perspective of the safe-by-design and science for regulation concepts.
