Multi-Micron Crisscross Structures Grown from DNA-Origami Slats

William Shih, Harvard Professor, is developing massive DNA origami structures. DNA origami refers to the practice of constructing physical structures out of DNA, typically using bundles of DNA bonded together to form a strong physical structure that can be used as rods. Will’s group is building self-assembling fabric structures, larger than 2 micrometers, from DNA origami which have fully addressable surfaces. Essentially, he can attach unique molecules to the surface to change the color or chemistry of the fabrics. These fabrics have the potential to be readable/writable nanoscale surfaces.
