Intracellular Redox Analysis In article number 2500560, Chen-Han Huang and co-workers present bimetallic Au/Ag nanoclusters that act as photo-responsive oxidase-like nanozymes. Under visible light, the clusters generate biologically relevant peroxyl radicals via Type I photosensitization, enabling rapid, reagent-free antioxidant sensing and redox tracking. This work broadens the applications of bimetallic nanoclusters as redox-active nanozymes in biomedical diagnostics and redox biology.
