Self-assembly is the spontaneous formation of an organized structure, pattern or phase from molecular unit blocks. Living organisms provide countless examples of extremely sophisticated and precise self-assembly processes. Self-assembly also provides unique opportunities in Materials Science. In this talk, I will discuss the different challenges involved in understanding self-assembly in biological systems and its implications for designing new materials. As concrete examples, I will present results in the problem of engineering nanoparticle supercrystals from DNA linkers, polymer nanocomposites and the characterization of signaling pathways as self-assembled processes. The role of new computational tools, such as Graphic Processing Units (GPU)s will be discussed. I will conclude with some open problems and perspectives.
