The work emphasized the unique properties that nanoscale structures can exhibit compared to bulk materials

The nanoscale is quite small, but materials of this size significantly impact many fields, from electronics to aerospace to robotics to medicine.

In an interdisciplinary collaboration, Northwestern Engineering’s Horacio Espinosa and Chad Mirkin explored how nanoscale materials could be organized into macroscopic structures that exhibit properties that exceed those of conventional bulk materials and those exhibited by natural systems. They implemented a novel approach to design and assemble nanoscale materials using colloidal crystal engineering with DNA, a methodology developed by Mirkin over the past three decades. This approach provides precise control over the arrangement of nanoparticles, enabling the creation of complex lattice structures….
