Supra-molecular agents running tasks intelligently (SMARTI): recent developments in molecular logic-based computation

The field of molecular information handling and processing from a Boolean starting point has grown
strongly during the past five years to make important contributions to the areas of intracellular
computation, delivery of functional species and information security. Additionally, there has been
consolidation of the original avenue of multi-input sensing devices, besides contributions to complex,
multivalued and reconfigurable logic systems. Small supramolecules form the majority of these devices,
though there is a strong showing from DNA and protein devices operating in a supramolecular fashion.
These devices serve as our agents to perform intelligent functions which we cannot do, such as within
living cells. The design and engineering of supramolecular systems is responsible for the origin of
molecular logic-based computation and for its longevity.
