Two different methods to self-assemble red- or yellow-luminescent nucleic acids-stabilized Ag nanoclusters (NCs) nanowires are presented. By one method, the autonomous hybridization-polymerization process between two nucleic acids leads to polymer chains consisting of sequence-specific loops for the stabilization of the red- or yellow-emitting Ag NCs. By the other method, the nucleic acid-triggered hybridization chain reaction (HCR) involving the cross-opening of two functional hairpins leads to sequence-specific DNA loops and a nucleic acid scaffold that stabilize the respective red- or yellow-emitting Ag NCs. The micrometer-long luminescent Ag NC-functionalized nanowires are imaged by AFM and confocal microscopy.
