13.8. THREE-DIMENSIONAL DNA LATTICES
Most of the DNA lattices described in this article have been limited to 2D sheets.
It appears to be much more challenging to assemble 3D DNA lattices of high
regularity. There are some important applications if this can be done, as described
in Figures 13.18 and 19.
Figure 13.18 illustrates the application of three-dimensional DNA lattices to
scaffolding of 3D nanoelectronic architectures. The density of conventional
nanoelectronics is limited by lithographic techniques to only a small number of
layers. The assembly of even quite simple 3D nanoelectronic devices, such as
memory, would provide much improvement in density.
