Resettable, Multi‐Readout Logic Gates Based on Controllably Reversible Aggregation of Gold Nanoparticles

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. Detailed facts of importance to specialist readers are published as ”Supporting Information”.
