A
key goal of DNA nanotechnology is the construction of periodic arrays in 3
dimensions (crystals). We have been successful in producing 3-D arrays from
tensegrity triangles. An image of
the sequence of the tensegrity triangle is shown below (a),along with images of
crystals (b).
The stereoscopic
images below show the molecular structure of the tensegrity triangle (a) and
the connection between two of them through a sticky end (b).
The
stereoscopic images below the surroundings of one triangle (a) and the
rhombohedron flanked by eight of the triangles (b). The red triangle is at the back of the rhombohedron, the
three yellow triangles are in a plane closer to the viewer, and the three green
triangles are in a plane yet closer to the viewer. The eighth red triangle which would be yet closer to the
viewer has been omitted for clarity.
