Self-assembly of protein arrays templated by 4 × 4 DNA nanogrids. (A) Schematic drawing of the DNA nanogrids scaffolded assembly of streptavidin. (Left) The DNA nanogrids, a biotin group is incorporated into one of the loops at the center of each tile. (Right) Binding of streptavidin (represented by a blue tetramer) to biotin will lead to protein nanoarrays on DNA lattices. (B) AFM image of the self-assembled protein arrays.
