Scientists use DNA technology to build tough 3D nanomaterials

Science
March 19 (UPI) -- Researchers at Columbia University have found a way to marry the versatility of DNA nanotechnology with the toughness of silica-based materials. DNA technology can be used to design self-assembling, complexly organized nanoparticle structures. Advertisement In theory, these structures can be designed for a variety of applications, but in reality, these structures are too soft and only stable in specific environs -- limiting their usefulness. Scientists described the novel fabrication process in a new paper, published Friday in the journal Science Advances. "A significant level of designability at nanoscale, through our assembly approach, combined with demonstrated robustness, opens opportunities to build targeted 3D nanomaterials from nanoparticles," Oleg Gang, professo...
