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.
