Seeing is believing: Nanoparticle crystals and core–shell crystals detect and amplify the presence of chemical and enzymatic analytes. These crystals are made insoluble in water by cross‐linking their surface with dithiols incorporating analyte‐specific groups. Upon addition of an analyte, these groups are cut, and the “punctured” crystals liberate millions of individual, brightly colored NPs (see
