(A) Supramolecular formation of PySSCou-containing ZG-20 NPs. The chemical structures of the components for the formation of PySSCou-containing ZG-20 NPs are shown in Figure S1. The ZG-20 NPs experience a fluorescence enhancement upon reaction with biological thiol compounds. (B) Schematic illustration of the working principle for the thiol-responsive PySSCou probe.
