"DNA: molecules form nanodevice scaffolding"
Richard Kiehl describes using DNA's unique lock-and-key mode of chemical bonding as a molecular-circuit assembly technique that he believes will be compatible with silicon-based electronics. A patterned silicon substrate, complete with interconnection pads, carries DNA-coded "tiles" that serve as breadboards for nanocomponents. The components are measured in angstroms, enabling densities of 10 trillion bits per square centimeter (1.6 trillion bits/inch2). In the prototype system, the nanocomponents are small gold clusters that have the ability to act as single-electron memory cells.
