Self-assembly is a pervasive natural phenomenon that gives rise to
complex structures and functions. It describes processes in which a
disordered system of components form organized structures as a
consequence of specific, local interactions among the components
themselves, without any external direction. Biological self-assembled
systems, evolved over billions of years, are more intricate, more
energy efficient and more functional than anything researchers have
currently achieved at the nanoscale. A challenge for human designed
physical self-assembled systems is to catch up with mother nature. I
argue through examples that DNA is an apt material to meet this
challenge. This work presents:
1. 3D self-assembled DNA nanostructures.
2. Illustrations of the simplicity and power of toehold-mediated
strand displacement interactions.
3. Algorithmic constructs in the tile assembly model.
