Abstract

Origami embellished with silver: DNA strands with specific sequences and covalently attached sugar moieties were used for the site-specific incorporation of the sugar units on a DNA origami scaffold. This approach enabled the subsequent site-specific synthesis and in situ immobilization of fluorescent Ag clusters at predefined positions on the DNA nanoscaffold by treatment with the Tollens reagent (see picture).
