Atomistic insight into nanostructured biomaterials

Using Supercomputers we perform molecular dynamics simulations of materials at scales of the order of a million of atoms. In this way we obtain unprecedent insight into the way that nanostructuration of biomaterials influence their properties. The examples considered here were how ionic domains modulate the elastic properties of biomembranes or how proteins interact with inorganic nanomaterials.
