A system including nucleic acid strands and unmodified gold nanopartcles is activated to perform programmed logic functions, using pH and DNA as inputs and the plasmonic‐related color change of gold nanoparticles as the output. The complexity of the logic devices can be simply enhanced by appropriate engineering.
