Abstract

Nanomaterials: a self-made world Self-replication is ubiquitous in living systems, but few artificial systems are able to copy themselves. It would be a very useful property in the world of materials fabrication, however, and Wang et al. now report a first step towards self-replication in that field. Using DNA tile motifs that can recognize and bind complementary tiles in a pre-programmed fashion, they first design tile motifs that form a seven-tile seed sequence, and then use the seeds to instruct the formation of a first generation of complementary seven-tile daughter sequences. Finally, the daughter sequences instruct the formation of seven-tile granddaughters that are identical to the initial seeds. As DNA can organize inorganic matter, this technique has the potential to lead to multiplicative copying of nanoscale structures and devices that are built from complex materials.
