| Abstract: | Single-stranded RNAs host fluorescent silver nanoclusters, analogous to previously studied Ag:DNAs. C and G homopolymers stabilize visible- to IR-emitting silver complexes at neutral pH in both RNA and DNA, but A and T/U do not. Cluster fluorescence is sensitive to sugar as well as base type. |
