Life is orchestrated by biomolecules interacting in complex networks of biological circuitry with emerging function. Progress in different areas of chemistry has made the design of systems that can recapitulate elements of such circuitry possible. Herein we review prominent examples of networks, the methodologies available to translate an input into various outputs, and speculate on potential applications and directions for the field. The programmability of nucleic acid hybridization has inspired applications beyond its function in heredity. At the circuitry level, DNA provides a powerful platform to design dynamic systems that respond to nucleic acid input sequences with output sequences through diverse logic gates, enabling the design of ever more complex circuitry. In order to interface with more diverse biomolecular inputs and yield outputs other than oligonucleotide sequences, an array of nucleic acid conjugates have been reported that can engage proteins as their input and yield a turn-on of enzymatic activity, a bioactive small molecule, or morphological changes in nanoobjects. While the programmability of DNA makes it an obvious starting point to design circuits, other biosupramolecular interactions have also been demonstrated, and harnessing progress in protein design is bound to deliver further integration of macromolecules in artificial circuits.
