Playing Tic-Tac-Toe with a Sugar-Based Molecular Computer

Today, molecules
can perform Boolean operations and circuits at
a level of higher complexity. However, concatenation of logic gates
and inhomogeneous inputs and outputs are still challenging tasks.
Novel approaches for logic gate integration are possible when chemical
programming and software programming are combined. Here it is shown
that a molecular finite automaton based on the concatenated implication
function (IMP) of a fluorescent two-component sugar probe via a wiring
algorithm is able to play tic-tac-toe.
