. Remarkably, two guanines bridge the central 17-silver-atom cluster with two additional isolated silver atoms, which are further stabilized through interactions with cytosine and adenine nucleobases. These findings provide new insight into how DNA sequences drive AgNC formation and tune spectroscopic properties, advancing the rational design of near-infrared-emissive nanoclusters with tailored optical responses.
