Photoinduced formation of stable Ag-nanoparticles from a ternary ligand-DNA-Ag(+) complex

Photoinduced formation of stable Ag-nanoparticles from a ternary ligand-DNA-Ag(+) complex

The combination of (i) the light-harvesting nature and excited-state redox reactivity of a cationic DNA intercalator, (ii) a conjugated Ag(+)-binding crown ether, and (iii) the stabilizing effect of DNA on AgNPs in one integral ternary complex enables the mild photoinduced formation of Ag nanopartic...
