Researchers from Duke University and Arizona State University have created tiny nanoscale structures shaped like vases, bowls, and hollow spheres by using threadlike molecules of DNA. These creations demonstrate the possibilities of a new open-source software program developed by the researchers that lets users take drawings or digital models of rounded shapes and turn them into 3D structures made of DNA. The software could also allow researchers to create tiny containers to deliver drugs, as well as molds for casting metal nanoparticles with specific shapes for solar cells and medical imaging.
