  1. Abstract: Self-assembly is beginning to be seen as a practical vehicle for computation. The assembly of DNA-based tiles into 2D periodic arrays had been reported several times with a variety of motifs. In our work, one layer of self-assembled DNA 2-D array will be used as the programmable template. Sequence dependent nano-mechanical DNA devices will be inserted into the array. Each device can enter into a bi-stable state, and that this state could be controlled as well by the sequences of DNA. This system can lead to the computation of an arbitrary boolean function or creation of 2D DNA layers satisfying specific properties.
