- 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, d

- Visual detection of copper(II) by azide- and alkyne-functionalized gold nanoparticles using click chemistry
-
(Figure Presented) Just one click, and the color's gone: In the presence of Cu2+ with sodium ascorbate as a reductant, gold nanoparticles that have azide- and alkyne-terminated groups undergo aggregation as the result of CuI-catalyzed click chemistry. This process can be monitored by eye without the aid of instruments (NPs=nanoparticles).
