摘要：

Clustering together: A shuttle-based fluorogenic cluster transfer, in which silver clusters (SCs) are directly transferred from a low-molecular-weight poly(acrylic acid) (PA) shuttle to a single-stranded DNA (ssDNA) tag on the protein of interest (see picture), proceeds with excellent specificity. Upon transfer, the cluster fluorescence increases more than ten times, which provides bright, photostable labeling. (Figure Presented). © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
