Description:

A DNA nanostructure consisting of four four-arm junctions oriented with a square aspect ratio was designed and constructed. Programmable self-assembly of 4 x 4 tiles resulted in  distinct lattice morphologies such as these two-dimensional nanogrids, which display periodic square cavities. Protein arrays and silver nanowire can be fabricated onto this nanotemplate grid for use in biosensor and electrical applications.  Above are AFM images of the 2D lattices (nanogrids) formed from the corrugated design. The right panel is a surface plot of a magnified region from the left panel.
