We have used antiparallel double crossover molecules as components to create 2-D DNA crystals. In addition to producing periodic arrays, we have also performed an algorithmic assembly. We have used this approach to organize DNAzymes and gold nanoparticles. In a major advance for nanorobotics, we have developed a cassette that can insert a sequence-dependent DNA device into a 2D crystalline DNA array.
In another advance using antiparallel double crossover molecules, we have made a two-state nanomechanical device. We have produced a robust sequence-dependent device. Further advances in nanomechanical devices are described in the link.
Future steps in this project include the synthesis of 3-D crystalline arrays (lattices), and exploring the relationship between order and symmetry.
