Directed self-assembly of block copolymers is a route to obtain tailored 3D patterns on the 10nm scale that have a high degree of order. These patterns are promising for multiple applications, including lithography and functional materials. In this talk, I will present our computational work on directed self-assembly of diblock copolymers templated by graphoepitaxial methods. In particular, I will show a new technique that we have pioneered for performing inverse self-assembly in which the input is a given target pattern and the algorithm provides an optimal template solutions for such pattern. Experimental results confirming the predictions will be also presented. Afterwards, I will also discuss about how one can then �dope� the system with other materials as could be nanoparticles and realize well ordered functional heterogeneous systems.  At the end I will present some future challenges and perspectives in this area.
