Beyond DNA: New Digital Polymers

Abstract

From a programming perspective, DNA is stunningly simple: a string of bits coding two types of interactions. The specific chemical form of DNA given to us by evolution imposes significant constraints on what is possible with DNA nanotechnology. In this paper, I propose three designs for new digital DNA-like polymers that retain the essential information-bearing properties of DNA while enabling functions not achievable with DNA such as greater stability, programmability, and precision.
