Abstract

Abstract : The warrior with a shield represents a unique Au–AgI dimeric nanostructure that is developed for sensitive and selective colorimetric detection of H2 S. Upon attack by H2 S, AgI (the shield) converts to Ag2 S, inducing a plasmonic shift of the connected Au nanoparticle (the warrior). The Au nanoparticle changes its color depending on the concentration of the sulfide, thus enabling a naked‐eye readout, as described by Jingbin Zeng, Yadong Yin, and co‐workers in article number1800515 .
