A wide diversity of molecular structures, chemical phenomena, and mechanisms can be marshalled to produce a large range of molecular logic operations according to the Boolean blueprint. Since the blueprint has produced society-changing semiconductor-based information technology, we can hope that molecular logic gates can interface with the venerable information handlers of biology especially at the cellular level. In the meantime, good progress is being made in the generalization of molecular logic. Some examples of the molecular-level implementation of single-input logic gates such as YES and NOT are outlined. This is followed up with molecular versions of double-input logic gates such as AND, OR, NOR, NAND, INHIBIT, and XOR. A half-adder is discussed as a prototypical number-processing system.
