Supramolecular interactions naturally involve information handling so that recognition takes place between two molecules. The gathering and processing (and to some extent, storing) components of information handling can be conveniently analyzed according to Boolean logic. Single-input YES and NOT logic can be discerned within information gathering operations, that is, sensing. A fluorescent case that is useful for monitoring blood electrolytes illustrates some of the concepts and mechanistic considerations involved. Double-input AND logic lies within some sensors with improved selectivity toward bifunctional molecular targets. Extension to triple-input AND logic gives rise to “lab-on-a-molecule” systems. These combine sensing with a rudimentary algorithm to allow a degree of decision-making regarding the gathered information. The unique ability of molecular information processors to succeed in small spaces barred to semiconductor devices is illustrated by molecular computational identification (MCID) tags. Molecular systems that display aspects of random access memory illustrate progress in sequential logic.
