We developed a design scheme for nanoparticles (NPs) to bring about their self-assembly into finite mesoscopic structures or architectures. Single-stranded DNA is grafted to the surface of the particles endowing them with highly selective, directional interactions through the hybridization of complementary strands. We have demonstrated in silico the successful formation of cubes, pyramids, boxes and even a model of the Empire State Building. We are currently working with experimentalists on closely related systems.
