A resettable logic system based on spiropyran‐modified gold nanoparticles that is capable of AND, OR, and INHIBIT logic operations has been constructed. Several methods can record the output of this process, including the naked eye, UV/Vis spectroscopy, determination of the ζ potential, and dynamic light scattering. These logic gates can also detect copper(II) ions in aqueous media.
