A new triple crossover triangle (TXT) motif for DNA self-assembly

A new triple crossover triangle (TXT) motif was conceived on the basis of the DNA triple crossover (TX) motif. The new motif is rigid and triangular prism-shaped, out of which 1-D. 2-D, and 3-D DNA structures can be assembled. The 1-D TXT array was self-assembled and was observed by the TEM with negative staining by uranyl acetate. The architectural schemes for 2-D and 3-D structures are presented.
