Self-Assembly of Lithographically Patterned 3D Micro/Nanostructures

On the nanoscale, it is extremely difficult and expensive to fabricate analogs of macroscale engineering, such as grippers. Drawing inspiration from biological fabrication in nature, engineers are seeking to self-assemble structures from the bottom up. The Gracias Lab at The Johns Hopkins University has developed a relatively easy, precise, and cost-effective process by which the 2D templates of semi-tethered "faces" can self-assemble into controlled 3D structures by utilizing the natural phenomena of surface tension as well as thin-film stress.
